FOREWORD The basic principle of the screw conveyor remains unchanged today from when Archimedes first used an internal type helix to remove water from the hold of a ship. With the technological innovations of the past cen.tury and a great deal of research in the field, screw (::onveyors have become precision pieces of equipment that can move materials either horizontally, on an incline or vertically. They can be used as feeders, distributors, collectors or mixers and can be equipped to either heat or cool while performing the task. With proper covers and gasketing they become weatherproof, dust tight and rodent proof. Their compact design allows them to fit easily into restricted areas that would otherwise be unsuitable for most types of bulk material handling equipment. They are simple to install and support and require very little maintenance. Per foot, they are undoubtedly one of the most economical types of bulk material handling equipment available today.

Material Analysis The initial step in engineering a screw conveyor is to analyse the material being handled and ascertain its physical properties in order that they may be thoroughly evaluated and understood prior to proceeding with the conveyor sizing and selection. These properties are discussed in further depth below.
Lump Size: The minimum diameter of a conveyor screw for a given application is determined by the maximum lump size of the material being handled. For this reason, it is necessary to thoroughly analyse the material and determine its maximum lump size and the percentage of lumps to total volume along with the minimum particle size and screen analysis when possible. With this information, proper conveyor sizing can be effectuated.
Flowability: The flowability of a material greatly affects the horsepower requirement of the conveyor in question. Flowability is related to the angle of repose of a material and therefore, fine free flowing materials can be handled at higher trough loadings with lower horsepower requirements than coarse, sluggish ones. Please refer to the Classification Code, Table 1 for further information.
Abrasiveness: The more abrasive the material being handled, the greater the wear the conveyor components are subjected to. For this reason, it is necessary to determine the abrasive quality of the material in question prior to sizing the conveyor. Abrasiveness can be determined by knowing a material's hardness on a Moh's scale and should this not be available the material can be compared with another known abrasive material.
Special Applications: These are additional the operation of the conveyor and are further entitled Special Applications and Specifications and 27 inclusive.
factors which can affect discussed in the section appearing on pages 26 '
Moisture Content: Material moisture content is also a factor that affects material flow. Excessively dry or wet products tend to flow easily, however, many develop sluggish characteristics when having a moisture content between the two extremes. This is not accounted for in the material tables which follow and such materials should therefore be reclassified. Duty Cycle: Machinery design also includes selection of the proper equipment for the usage it will receive. A conveyor operating for 2 hours per day does not require the same heavy construction as one designed for 24 hour usage. This appliesto material thickness and drive sizes alike. Likewise. shock loads to which the equipment and drive are subjected to are an important consideration. Treatment of these factors are not described in suitable enough depth here. however, as previously mentioned. our engineering staff will gladly assist you to determine the best conveyor design.

3. Determine
the Design Capacity
Screw conveyors that employ standard, full pitch flighting have a Design Capacity equal to their required capacity. Required capacity was determined in Step 1 and is the maximum amount of material per hourthe conveyor in question must handle. DesIgn Capacity, however, is not equal to required capacity when a modified flighting configuration (such as half pitch) is used. This will alter the output of the conveyor and therefore, when using a modified flighting, itis necessary to multiply the required Factors appearing in Table 3 in order to obtain Design
Capacity
that is then used to establish
capacity by the Capacity th'e Design Capacity. It is
the conveyor
diameter
and
speed. TABLE 3

4. Establish the Diameter and Speed After having determined the material classification and the' Design Capacity of the conveyor in question, refer to the Capacity Charts, Table 4, on Pages 18 and 19. The applicable chart forthe material in question is determined by referring to the "Capacity Chart No."column in Table 2, Material Characteristics. Deterrf1ine the appropriate conveyor diameter by referring to the "cubic feet/hour at maximum A.P.M." column. Once the proper conveyor diameter has been selected, verify Table 5 to insure that the diameter selected is large enough to handle the material size in question. Should the lump size be too great for the diameter selected, proceed to the next larger diameter that will handle the material. One should note, however, that this applies only to materials comprised of hard lumps that will not break up in the conveyor. Speed is now determined by dividing the Design Capacity arrived at in Step 2 by the relevant figure in the "Cubic Feet/Hour at 1 A.P.M." column of the Capacity Chart in question. For example, a9" diameter conveyor as shown in .Capacity Chart 5, Table 4, will handle 80 cu.ft./hour at 1 A.P.M. Thus, if the conveyor in question is to handle 640 cu.ft./hour it must turn 80 A.P.M. (640cu.ft./hr+ 8 cu.ft./hr. @ 1 A.P.M. = 80 A.P.M.).

Now proceed to Component Selection, Table 6 to determine the type of bearing material recommended for the application. This data will be used in establishing the required conveyor horsepower. The recommended bearing types shown in Table 6 are those most often used with each of the Component Groups shown. Bearing selection however is often affected by other constraints such as the type of product handled, temperature or noise level.

Conveyor flighting deviating in pitch only requires the same horsepower as standard flighting. If a modified flighting is used, such as ribbon flight, additional power will be required.

Determine Shaft Size The maximum horsepower that may be safely applied to a given shatt, pipe or coupling bolt size at any given speed is determined by verifying their particular torque rating as shown in Torque Capacity, Table 10 found on page 22. These ratings are based on Schedule 40 conveyor pipe, cold rolted shafts and standard grade coupling bolts. For horsepower ratings of heavier pipes, high torque shafts or bolts and stainless steel or other materials, please contact our engineering department. To use Table 10, determine the intersection point between the conveyor speed ard the motor horsepower and read the shaft size, conveyor pipe and standard screw size along the bottom.

857 per
Aeferring now to Capacity Chart 8, the correct conveyor diameter is selected by looking down the "Capacity in Cubic feet @ maximum A.P.M." column until the proper size conveyor is found for 925 cu.ft./hr. This is found to be a 20" diameter unit. Lump size must now be checked using Table 5 and it is found that the minimum conveyor diameter required to handle 4" lumps at 10% of the total volume is 16". Thus, the 20" conveyor is satisfactory. Next, one finds that a 20" diameter conveyor will carry 31 cu.ft./hr. @ 1 A.P.M. from the next column over. Now by dividing 925 cu.ft./hr. by31 cu.ft.fhr. @ 1 A.P.M. we obtain a conveyor speed of 30 A.P.M.

The Component Group is now established as being 3D from Table 2. Next, by referring to Table 6, we find that hard iron bearings are recommended for a 3D application.

This horsepower figure is now multiplied by the Modified Flight Factor taken from Table 8 for 1 paddle per pitch. Thus 6.12 X 1.29 = 7.89 H.P. Using 7.89 H.P., we verify Table 9 and select a 10 H.P. motor for the requirement. Torque capacity is now verified using Table 10and it is found that a 3-7/16" diameter shaft is required to transmit the motor H.P.. From the Component Selection Shart, Table 6 we find that for a 3D Component Group using a 20" diameter conveyor screw with 3-7/16" shafts, a 20S724 unit is required witha 1/4" thick trough and 12 ga. covers. Page 28 may now be referred to for additional layout data and details.
BEARING
RECOMMENDATIONS The selection of a bearing material for use in intermediate hangers is one that is based largely on experience coupled with consideration for the particular characteristics of the material in question. The principal factor affecting bearing performance between various bearing materials is a rating factor known as PV (pressure velocity). This rating is a mathematical expression of PIA (pounds per inch of projected area) of load times SFM (surface feet per minute). Thus, the PV value is the maximum load and speed that a bearing may be subjected to. The following list deals individually with the most popular types of screw conveyor bearing materials indicating their particular areas of strength and their restrictions. While this list covers most applications, it is far from being complete as to the number of bearing material on the market today. Should special applications or conditions be encountered, Continental engineers will gladly assist in the selection of a suitable material.
Babbitt and Bronze Bearings Babbitt and bronze bearings have traditionally been used in applications where mildy abrasive, irregular or lumpy materials are encountered. Because of their need for oil or grease lubrication, they are unaccpetable in applications where contamination is a deciding factor. Babbitt bearings have a temperature limitation of 130°F while lubricated bronze are limited to 220°F. The temperature limit for bronze can be extended by using special high temperature alloys and/or synthetic lubricants. The maximum PV of babbitt is approximately 30,000 with a maximum P of 1500 and V of 1200. Bronze on the other hand has a maximum PV of 75,000 with maximum P of 3,500 and V of 750. 24
Self Lubricated
Bearings
Self lubricated bearings such as oil impregnated hard maple, graphited bronze, commercial carbon, sintered bronze and thermoplastic or reinforced fibre have become very popular for applications involving mild to moderate abrasiveness with irregular or lumpy materials. . Oil impregnated wood has proven to be an extremely good bearing material. Its major drawback is its inability to withstand highly abrasive cond.itions such as encountered when moving aggregates or sand. Their temperature limit is approximately 180°F. In mildly abrasive conditions, wood has the property of embedability which permits grit to become embedded in the bearing sidewall then film over with lubricant thus holding the shaft harmless. Its maximum PV is 15,000 with a maximum P of 2,000 and V of 2,000. Its total PV approaches that of babbitt and can carry higher speeds or loads individually. Thermoplastic bearings such as ultra high molecular weight polyethylene (UHMWP) and nylon are the most regularly encountered thermoplastics. Both operate effective1y in damp conditions, however, UHMWP is best suited to wet aplications such as ice or fish offal conveyors because of its low rate of water absorption thus minimizing shaft seizure due to bearing swelling. Nylon on the other hand absorbs water at a much higher rate which can lead to swelling problems. Temperature limitations of UHMWP are 180°F while nylon is 250°F. Abrasion resistar:lce of UHMWP is outstanding providing PV limitations are not exceeded. This same material IS used as chute liners in the gravel industry. The maximum PV of UHMWP is 4,000 with a maximum P of 1,200 and V of 50. Nylon on the other hand has a maximum PV of 3,000 with a maximum P of 400 and V of 350. Graphited bronze bearings are useful in certain applications and have a maximum PV of 50,000 with a maximum P of 1,500 and V of 1,200. Their maximum operating temperature is 500°F. For higher temperature applications, commercial carbon bearings can be used as their temperature limits are approximately 600°F.
Hard Iron Bearings Hard iron bearings cast in chilled white iron or Ni-Hard@ materia) are used when handling excessively abrasive materials. They must be used in conjunction with hardened coupling shafts, which, depending on the circumstances can be achieved through induction hardening or hard surfacing the shaft in question. Hard iron bearings are not normally lubricated and have a maximum operating temperature of 500°F. The maximum PV of hard iron is 75,000 with a maximum P of 8,000 and a V of
35. Because of the absence of lubricant when using hard iron bearings with hardened coupling shafts, it is necessary to limit the operating speed using the formula below in order that wear may be kept to a minimum and that excessive squealing noise caused by dry metal on metal be eleminated.

encountered. Abrasive Materials Abrasive materials have a tendency of causing excessive and accelerated wear on screw conveyor components and should be carried at low cross sectional loads and slow conveyor speeds. For excessively abrasive materials or conveyors subjected to heavy, continuous service, heavy duty components should be specified and abrasive resistant, hard surfaced materials or alloys should be considered for the application.
Contaminable
Materials
Easily contaminable materials such as foodstuffs and certain chemicals require special components and construction not necessarily found in standard conveyors as outlined in the selection process. Such special components and features often include non lubricated intermediate hanger bearings, end bearing seals, tightly sealed covers, and often drop bottom troughs for easy access and cleaning of the conveyor. Certain applications may also require continuously welded flighting on one or both sides of the pipe and special finishes on the welds to minimize roughness and alleviate contamination. Many materials will also require stainless steel to eliminate corrosion.
Corrosive
Materials
When corrosive materials are encountered it is advisable to use components manufactured of stainless steel, aluminum or other resistant alloys. Hot dip galvanizing may be used in non abrasive applications.
Degradable
Materials
Materials which have a tendency to break up or separate easily, thereby affecting quality, should be handled in larger diameter, slower turning screw conveyors to reduce material agitation.
Extreme Temperatures When handling materials of extreme temperature, it is necessary to construct the conveyor with special components and alloys designed to meet these conditions. (With the use of a jacketed type trough, it is possible to either heat or cool the material while conveying and keep it within a safe operating temperature). Please consult our engineering department for their recommendations.
Fluidizing
Materials
When handling materials which tend to aerate easily and decrease in density, thereby increasing in volume, it is important to take into account the areated density in order that the conveyor size, speed and horsepower can be adjusted in consequence.
Hygroscopic
Materials
Hygroscopic materials which readily absorb moisture must be handled in tightly sealed conveyors that exclude the exterior
26
atmosphere. The fact that the material will also increase in density and become more sluggish when in contact with moisture must also be taken into account when determining conveyor size. horsepower and speed.

DATA
TABLE 11 HAND OF CONVEYOR When selecting comp0nents for your screw conveyor, please refer to Typical Conveyor Layout, Table 12, and the accompanying diagram for the dimensional standards and recommended layout arrangements.
Conveyor
Screws
Conveyor screws are available as either right or left hand units. Right hand will be supplied unless otherwise specified. In order to determine the "hand" of a conveyor, refer to Hand of Conveyor, Table 11. Use standard length conveyor screws whenever possible. The carrying face of the screw, which moves the material being conveyed is free of lugs for unimpeded flow. Lugs are positioned on the back or non carrying side of the screw at each end to guard against the flight folding back. It is therefore essential that a screw designed for right hand operation be used that way and vice versa for left hand. Bi-directional conveyor screws can be furnished for specific operations. Flighting should be omitted over the last discharge opening and flight ends at hanger positions should be set opposite each other for continuous flow of material across the hanger space. Note that if the edge of the flight on the near side of the conveyor screw slopes down to the right, the screw is right hand and if it slopes downward to the left, the conveyor screw is left hand.

sections of screws and
Hangers must be placed clear of inlet openings. They can be placed at trough joints as they are designed with spacer bars wide enough for this purpose. Hangers may be fitted with a wide variety of bearing materials to suit a diverse range of screw conveyor applications.
Couplings
and Shafts
Coupling, drive and end shafts connect and transmit power to the conveyor screws. It is imperative that the shafts selected be of sufficient strength to handle the horsepower and load Imposed on them. Their horsepower rating may be verified as shown in Torque Capacity, Table 10, Page 22. Most conveyor systems are made up of standard components and in order to replace or renew an intermediate section of conveyor it is necessary to dismantle the conveyor from one end. The time involved to effectuate this work can be greatly reduced by using Quick Release Keys on the conveyor screws as shown on page 41. These enable an entire section of screw to be removed from the center of the conveyor without disturbing preceding sections.
Trough Ends Trough incorporate 28
ends support the conveyor screw and the trough. They a bearing assembly to maintain clearance between the
trough and conveyor screws, and, depending on the direction of material travel, incorporate a thrust bearing to maintain clearance between the conveyor screws, hangers and trough ends. This provides for smoother operation, lower power requirements and less wear on the hangers, bearings and other vital components. The standard duty Type E or the heavy duty Type H thrust bearings will absorb thrust in either direction, however it is preferable that the thrust bearing be positioned at the discharge end of the conveyor. Seals are incorporated into the trough ends to prevent leakage into or out of the trough. They also provide added protection for the end bearings and shafts from the material being handled. Shelf type trough ends are very often used when handling hot materials in order that the bearing and drive can be separated by some distance from the hot trough. They are also used when handling fine or very abrasive materials which require more effective sealing than can be achieved with standard seal plates under flange bearings. The seals generally used in these cases are the Split Gland or the Packed Gland types ( see page 69 ). When extreme shaft concentricity is required a double pedestal shelf type trough end is used. This minimizes shaft mounted reducer wobbling.
Troughs and Covers Numerous trough and cover configurations are available for varying applications. Standard lengths should be used whenever possible. See the section on troughs and covers for specific applications of each. Gasketing is available between the trough and cover depending on the application.
MATERIAL
INPUT AND DISCHARGE Care should be exercised in controlling the loading of a conveyor since it is designed to handle a specific maximum volume of material. Difficulties arise when the conveyor is fed from a storage medium without the use of input volume controls. If the rate of material flow is not inherently self regulating or cannot be regulated by other controls, a Screw Feeder or another flow control should be incorporated into the system in order that a smooth and constant flow will be delivered to the system. By doing so, all surge loads are avoided. Flow regulation by Screw Feeder and Rotary Feeder are discussed in further depth below.
Screw Feeders Screw Feeders consist of a specially designed conveyor screw enclosed within a tubular housing or a trough with a shroud cover. They are used for the removal of material at a predetermined rate from a storage medium regardless of the existing head of material. For further information on these units see the section entitled SCREW FEEDERS on page 31 of this manual.
[~;I~~~~~~~~~~ 29
Rotary
Feeders
Rotary feeders employ a cylindrical rotor with pockets volume which deliver a constant flow of material. Their output regul.ated by the speed of rotation of the rotor. These frequently be driven from the conveyor drive or end shaft necessity of an additional drive for the feeder itself.

Inlets
Installations frequently require the use of conveyors with multiple inlets for feeding from several different sources either individually or simultaneously. When only one inlet will be open at any given time, a gate or cut off device may be restricted to a maximum opening that will not allow overloading of the conveyor. When more than one gate will be open, considerable care must be taken to limit the flow from each so that the aggregate rate is not in excess of the conveyor design limit.

Dead Loads Screw conveyors loaded directly from a storage medium above the conveyor with a free flowing material are subject to varying dead loads due to the hydrostatic head of material and the associated loads created when moving the material from under itself. This problem can be circumvented by using a side type inlet incorporating a slide gate if necessary to relieve the screw from excessive material pressures. Screw rotation should always be towards the opening to en~ure a constant flow rate.
30
Impact Loads Frequent requirements are such that materials must fall vertically to the conveyor inlet creating the possibility of impact damge to the conveyor screw due to the inertia of the material particles or lumps. This condition may be overcome by using deflector plates or cushion chambers in the inlet spout.
Discharge
Spouts
Most discharge spouts are of standard design as shown on page 78 of this manual, however special units can be built to adapt to specific machinery and can be supplied flared or longer than standard. In all cases, flighting is usually eliminated beyound the midpoint of the last discharge opening on a conveyor in order to effect complete discharge of the material and alleviate any possibility of material carry-over. When conveying materials that are fluid or easily aerated it may be advisable to install longer than standard discharge spouts. Intermediate discharge spouts may be fitted with a variety of control gates or slides. These slides are often manually operated however they can also be actuated by rack and pinion assemblies, hydraulic or pneumatic cylinders or by special electric gear motors complete with limit switches. ~tis advisable that the last discharge spout on conveyors with multiple discharges or the discharge spout of units with a single discharge be furnished without a slide of any kind on prevent possible damage to the conveyor in the event of operation with the slide closed.
SCREW FEEDERS A screw feeder differs from a screw conveyor in that it is designed to regulate the volumetric rate of material flow from a hopper, bin or storage unit. The inlet is flooded to 100% load capacity and by incorporating changes to the flighting (diameter, pitch, etc.) and the speed of the feeder screw, it is possible to govern the rate of material discharge. The style of flighting used in a screw feeder is dependent upon the characteristics of the material being transported and either a regular pitch, modified pitch or a modified diameter flight is used. Screw feeders are usually equipped with a shroud cover for a short distance beyond the inlet opening. This helps prevent flooding of the conveyor with material. When very free flowing materials are being handled it is often necessary to use extended shroud covers, tubular housings or short pitch flighting for positive material control.
I{!:I continantal,1 31
Uniform Diameter and Pitch Feeders This type of screw feeder is generally used for handling fine, free flowing materials. Because the regular diameter and p.itch brings about material flow from the forepart of the inlet and not along its entire length, this type of unit should only be used when a hopper is to be completely emptied or where inert or dead areas of material overthe ir)letdo not pose a problem. Should the material being handled be on an extremely fine or free flowing nature, a shortened or half pitch flight should be used to prevent flooding and overloading of the conveyor being fed.
Variable Pitch Feeders Screw feeders having a variable pitch are generally used in conjunction with a screw conveyor in which the material is choke fed from a bin or hopper. The short pitch handles the full cross sectional load and .as tt,e mat~rial is tran~ferred int
Tapered Diameter Feeders Screw feeders having tapered flights are generally used to convey materials containing a considerable percentage of lumps They are also extensively used when it is desirable to draw material from a bin or hopper along its entire length thereby eliminating dead or inert material In the forepart of the opening. Using a tapered flight feeder instead of a regular flight will, in most cases, especially when the feed or inlet openings is 10ng...f6onsume much less horsepower.
32
Multiple Diameter Feeders This isa combination feeder and conveyor, the phystcal dimensions being variable on each. The small diameter feed end operates at full cross sectional loads and, upon reaching the larger diameter, reduces to a safer level in proportion to the change in diameter. These units are generally employed when it is undesirable to use a variable pitch section under an inlet be it due to the need to eliminate dead areas, because of an excessively long inlet from a bin or hopper or because the lump size of the material in question is not compatible with the short portion of the variable pitch. It is worthwhile to note here that the feeder portion of a multiple diameter screw can be tapered should it be desirable.
Live Bottom Feeders Live bottom feeders are used to discharge materials from straight sided bins and are composed of several horizontal screws side by side which cover the complete area of the bin bottom. The material is therefore drawn out equally from the full width into a collecting conveyor that runs at right anglesto the bin bottom screws. The live bottom feeder is used to discharge materials that have tendency to pack and bridge easily under pressure.

INCLINED
S~:REW CONVEYORS Screw conveyors may be used in the inclined plane and when space allows, this can be a very economical method of both elevating and conveying simultaneously. It is most important however to understand that as the angle of inclination increases, the capacity of the given unit rapidly decreases. The critical angle at which it becomes most difficultto convey material on an incline is 450. As one approches this angle capacity drops very dramatically and once past this critical point and on towards 900, the efficiency of the unit increases again. Numerous methods of conveying on an incline are used among which are shorter than standard pitch, tubular housings or extended shroud covers. It is also necessary as the angle of inclination becomes greater to increase the conveyor speed in order to overcome the tendency of the material to fall back upon itself. Inclined conveyors can rarely be used as feeders for accurately measuring material flow. If an accurate flow rate is necessary, a separate horizontal feeder conveyor is required. Since additional power is required to convey material on an incline and this power is a function of material density, consistency and vertical lift, we suggest that our Engineering Department be contacted for specific recommendations application.

VERTICAL
SCREW
CONVEYORS The vertical screw conveyor is an extremely efficient and effective method of elevating and distributing bulk materials. As a ruleofthumb, if a material can be handled by a horizontal screw conveyor, it can also be handled in the vertical plane. By having fewer moving parts, the vertical screw conveyor does away with many of the difficulties commonly encountered with other types of elevating equipment. Amongst the numerous advanteges of this type of unit is its flexibility of design and arrangement. One can convey up to 6000 cu.ft. per hour using a 16" diameter unit to a height of about 75 feet depending on material weight and the drive arrangement. These units are space saving and transfer material from the horizontal to the vertic:al plane very efficiently. Positive discharge is achieved in any direction and little or no material segregation or degradation occurs throughout the process. Since judgement and experience in conveying are required we again suggest you contact our Engineering Department for our specific recom mendations.
DRIVE
ASSEI\1BLIES
AND
ARRANGEMENT
Numerous combinations and types of drives are available for screw conveyors. Some of the more frequently used drives and mechanical arrangements are described below.
rlJj Screw Conveyor Drives Screw conveyor drives consists of a modified shaft mounted reducer complete with a V-belt drive and motor mount in an integral unit. This assembly combines the reducer output shaft, conveyor thrust bearing, end seal and adaptor flange for mounting integrally to the trough end. The electric motor can be mounted in both the horizontal or the vertical plane thereby adding to these units versatility.

Shaft Mounted Reducers Essentially very similar to the screw conveyor drive, this type of unit requires the use of a thrust bearing, drive shaft and seal assembly. As with the screw conveyor drive, it is possible to combine the motor mount integrally with the reducer unit, and power is transmitted through a V-beltdrive. Such a unit is usually used where special sealing arrangements are required on the conveyor shafts, such as a packed gland seal, or where very high horsepower must be transmitted which is not within the parameters of the screw conveyor drive.

The former is traditionally mounted on a scoop base attached to the trough end while the latter is mounted directly to the top of the conveyor or on a adaptor base or base plate beside the conveyor. These units are used in instances where high horsepower is being transmitted or when a variable speed gearmotor is used to vary the feed rates of a metering screw.

Other Drives and Configurations Numerous other methods of driving a screw conveyor are available among which are variable speed D.C. motors with SCR rectifiers, hydraulic drives or variable pitch sheaves between motor and reducer. Also, when inertia loads are encountered when starting heavily loaded conveyors or when high horsepowers are used on large or long conveyors, fluid couplings should be incorporated in the drive arrangement. We suggest you contact our Engineering Department for specific suggestions and recommendations regarding such matters.
SPECIAL
FABRICATION
MATERIALS
Screw conveyors are normally fabricated of low carbon, hot rolled steel plate with the exception of the drive, end and coupling shafts which are of cold rolled bar stock. Certain materials and conditions however require the use of materials other than mild steel. These materials and their advantages are discussed in further depth in the following paragraphs. Further information and assistance can be obtained from our Engineering Department for your particular applications.
Hard Surfaced
Conveyor
Screws
Conveyor screws that will be in contact with highly abrasive materials are often hard surfaced using fusible alloy hard surfacing materials or hard facing electrodes. These materials are applied to the flight surface in a width proportional to the conveyor's cross sectional load. These dimensions are given in Table 13. The dimensions given pertain to standard application however for extremely abrasive conditions or higher than normal trough loadings, it may be advisable to harden the full flight face, periphery and even the pipe.

Helicoid Designation The letter 'H' indicates screw conveyor with helicoid flighting. The figures to the left of the letter indicate the nominal outside diameter of the conveyor in inches. The first figure following the letter is twice the diameter of the couplings in inches. The last two figures indicate the nominal thickness of flighting at the outer edge in 1/64". Thus 12H408 indicates a 12" diameter helicoid conveyor for 2" couplings with flighting 8/64" or 1/8" thickness at outer edge. Due to the nature of the forming process, the periphery of a helicoid flight is approximately 1/2 the thickness of the material at the root where it is welded to the pipe. Because most wear is concentrated on the periphery, helicoid flights are less suitable for handling abrasive materials than sectional flights.

System for Standard
Conveyor Screws
screws are supplied with right hand flighting unless ortherwise specified. screws are supplied in standard lengths as shown on pages 42 through 46 unless
ortherwise specified. Flighting will cover the entire length of the conveyor pipe unless otherwise specified. Conveyor screws are fabricated of carbon steel unless otherwise specified. For information regarding materials in which conveyor screws may be obtained, see Special Fabrication Materials, page 38.

CONVEYOR SCREWS Helicoid
Conveyor Screws:
Helicoid flighting is formed by cold rolling special analysis strip into a continuous helix that produces a work hardened, smoothly finished flight surface. The flighting is then fastened to the pipe by intermittent welds with steel end lugs at each extremity to reinforce the tips. They may also be continuously welded on either one or both sides if so required. The pipe has seamless internal collars inserted and plug welded in both ends to accept the shafts. Both helicoid and sectional flighting of the same diameter and shaft size are interchangeable.

Sectional Flights: Sectional flights are formed from steel plate with a lead slightly longer than their pitch. This assures a tight grip when mounting them on the pipe. They are available in all standard sizes and can also be supplied in special diameters, pitches, thicknesses and pipe sizes.
Ribbon Flights: Ribbon flights are commonly used to handle sticky or gummy materials which normally build up at the pipe of flight junction point. Their open design minimizes this problem. They are also used for mixing dry materials in transit as long as the cross sectional load is greater than the face of the flight. The pipe has seamless internal collars inserted and plug welded in both ends to accept the shafts. Ribbon flight can be supplied in special diameters. pitches, thicknesses, pipe sizes and shaft diameters as well as in a variety of materials such as stainless steel, Inconel and Monel.
Paddle Conveyor Screws: Paddle conveyor screws are commonly used to mix material in transit when conveying efficiency is not important. The paddles are bolted through the pipe and are infinitely adjustable. The pipe has seamless internal collars inserted and plug welded in both ends to accept the shafts. Paddle screws can be supplied in special diameters, pitches, thicknesses, pipe sizes and shaft diameters as well as in a variety of materials such as stainless steel, Inconel and Monel.
Cut and Cut & Folded Flights: Notches cut in the periphery of a conveyor screw creates a very effective mixing action with most materials, particularly at high speeds. By folding over the cut, a more violent mixing action is achieved since the material is spilled over itself. The cut flight is also useful for moving materials which tend to pack while cut and folded flights are useful in cooling, heating or aerating light substances.
Internal
Collars, Coupling
Bolts and Quick Release Keys:
Internal collars are used in all types of conveyor screws to create a close fit between the inside diameter of the pipe and the outside diameter of the shaft. When purchased separately they are not drilled for the coupling bolts as the pipe ends are always drilled after assembly. Coupling bolts are machined from analysis steel with the thread cut to the proper length so as only the bolt shank is in contact with the coupling shaft and pipe, thereby ensuring full torque capacity and minimum wear. Special self-locking nuts are provided to prevent the nut from working loose during operation which can lead to damage and downtime. Quick release keys allow for the removal of an intermediate section of conveyor without dismantling the entire screw conveyor. To remove a section, the intermediate bolts are removed, the key is removed and the entire section simply lifts out while the shafts remains in position in the trough.

CONVEYOR SCREW SHAFTS
Drive Shafts:
Screw conveyor drive shafts transmit the rotary motion from the drive unit to the conveyor screw. They are manufactured of high quality, cold drawn steel to close tolerances for the proper bearing clearances. Coupling bolt holes are jig drilled for perfect alignment and key seats are precision milled to insure proper assembly. For applications requiring higher torque capacities, they can be supplied in high carbon steel. They are also available in stainless steel. Contact our Engineering Department for further information.
End Shafts: End shafts are designed to provide support of the final screw section. They are manufactured of high quality, cold drawn steel to close tolerances for proper bearing clearances. Coupling bolt holes are jig drilled for perfect alignment. They are also available in stainless steel.
Coupling Shafts: Coupling shafts are designed to transmit rotation between individual conveyor screw sections and to provide intermediate radial support through hanger bearings. They are manufactured of high quality cold drawn steel and have jig drilled bolt holes for perfect alignment. They are available in standard configuration for use with intermediate hangers and in close coupled configuration where the omission of hanger bearings is desireable. For use with hard iron bearings they are induction hardened to increase their wearing capacity. For applications requiring higher torque capacities they can be supplied in high carbon steel. They can also be supplied in stainless steel. Contact our Engineering Department for further information.

HANGERS
Style 226: The Style 226 hanger is the most commonly used in screw c:onveyor applications. Its narrow size and low profile maintains rigidity without compromising the material flow. It is designed to mount flush with the trough flarlges and therefore will not obstruct the trough cover which makes its use desireable with dust and weather tight covers.
Style 220: The Style 220 hanger is identical to Style 226 with the exception that it is designed for mounting directly to the top of the trough flanges. If it is to be used in conjunction with trough covers, the cover joints must coincide Y/ith the hanger positions.
Style 270: The Style 270 hanger is furnished with a self aligning, sealed ball bearing. This feature reduces friction and thus lowers horsepower requirements making such units desireable for long conveyors or those operating at high speeds. Due to the nature of the ball bearing seal they are not recommended for use in "dirty", gritty or abrasive conditions. An Alemite grease fitting can be supplied in the event that regreasing is desired.
Style 326: The Style 326 hanger is used in applications where hot materials are conveyed which can bring about linear expansion of the conveyor sc:rew. The hanger support bar is free to slide on angle guide bars to compensate for unequal expansion between the trough and conveyor screw. Its construction is similar to Style 226 and thus maintains all the advantages thereof.
Style 30: The Style 30 hanger is used when mounting a hanger to the top flanges of the trough cannot be achieved. It mounts to the non-carrying side of the trough and thus minimizes obstruction to the flow of material.
Flared Trough Hangers: Flared trough hangers are available in any of the above configurations adaptation to flared troughs as shown on page 76 of this manual.
for
Hanger Bearings: Hanger bearings of oil impregnated wood, UHMW polyethylene, nylon, hard iron or babbitt can be supplied for Styles 226, 220, 326 and 30. Numerous other materials are available for special applications as shown on page 25 of this manual. Style 270 on the other hand is available using only the ball bearing assembly.

TROUGH ENDS Trough Ends With Feet: Trough ends with feet are the most commonly used trough ends. The bottom flange foot is used to support the conveyor and is complete with slots for bolting the unit in position. All holes are jig punched to assure a proper fit to the trough end. The flange bearing is bolted in position to the trough end with a bolt pattern dependant on the style of bearing used. It is therefore necessary to stipulate the type of bearing when ordering.
Trough Ends Without
Feet:
Trough ends without feet are of identical construction to those with feet with the exception that the trough is fixed in position using separate flanged feet or saddles. As with trough ends with feet, it is necessary to specify the type of bearing used when ordering.
Outboard
Bearing Trough Ends:
Outboard bearing trough ends are used in conjunction with split gland or packed gland seals. A shelf welded to the trough end acts as a pedestal to which the pillow block bearing is bolted. The shelf type trough end is interchangeable with all other trough ends and is particularily suitable for applications conveying hot or abrasive materials from which the bearing should be isolated. It is necessary to specify the type of bearing used when ordering.
Double Outboard
Bearing Trough Ends:
Double outboard bearing trough ends are used in conjunction with two pillow blocks for applications that require extreme rigidity and concentricity of the conveyor shaft. They are most often used at the drive end when a heavy shaft mounted speed reducer is being used to drive the conveyor. As with single outboard bearing trough ends it is necessary to specify the type of pillow block used when ordering.
Discharge
Trough Ends:
The discharge trough end is used when material is to flow directly from the end of the trough. Due to its size, it is necessary that the trough' loading not exceed 45% or it will restrict material discharge. It is available with either a bailor a sleeve type flange bearing which must be specified at the time of ordering.

TROUGH END BEARINGS
Ball Bearing Flange Unit: Flange bearings of this type are commonly used on the non-thrust end of a screw conveyor. The gray iron housing incorporates a heavy duty single row ball bearing that is selfaligning and has a good radial load capacity.
Roller Bearing Flange Unit: Roller bearing flange blocks of this type incorporate a heavy, rugged gray iron housing and two tapered roller bearings. The units have a high radial load rating with good thrust capacities. They also will handle slight angular shaft mislalignment.
Sleeve Bearing Flange Unit: This is a babbited type flange bearing that is used in applications that do not require or are unsuitable for conventional ball or roller bearings. They have no misalignment capabilities however do have good radial load capacities.
Roller Bearing Pillow Blocks: Are of similar construction however are used in conjunction
to the roller bearing flange unit with shelf type trough ends.
Ball Bearing Pillow Blocks: Are of similar construction however are used in conjunction
to the ball bear.jng flange unit with shelf type trough ends.

TROUGH END BEARINGS
Sleeve Bearing Pillow Blocks: Are of similar construction however are used in conjunction
to the sleeve bearing flange unit with shelf type trough ends.
Type E Thrust Bearings: ~,...~
~
The Type E bearing is the most commonly used thrust bearing and is designed to handle medium to heavy thrust loads in either direction while maintaining good radial load capacities. Thrust is created opposite to the material flow in a screw conveyor which will cause accelerated component wear if not contained. It is thus advjseable to incorporate a thrust bearing, preferably at the drive end, to keep the conveyor screw in tension. The thrust is contained by snap rings on the shaft on each side of the bearing assembly.
Type H Thrust
Bearings:
The Type H thrust bearing is used for cases in which extreme thrust loads are encountered. The shaft is shouldered and set between two high capacity roller bearings in order to absorb thrust in both directions. The assembly incorporates lip type seals within the housing thus eliminating the need for external trough end type seals.
Collar & Washer Thrust Assemblies: Assemblies of this type are used in conjunction with sleeve type bearings in applications where light thrust loads are encountered. The collar, washer and grooved shaft are mounted outside the trough and are intended for use at the discharge end of the conveyor with the conveyor screw in tension. Bronze Washer Thrust Assemblies: The bronze washer assembly is mounted inside the conveyor trough at the inlet end and is designed to handle light, compression thrust loads. It consists of a bronze washer mounted between two machined steel washers fitted between the trough end and pipe. Due to its interior location it is exposed continuously to the material being conveyed and thus in some instances has a limited life.

TROUGH END SEALS
Packing Seal Housing: Packing type seals are used in conjunction with waste packing or a cartridge type lip or felt seal. They bolt between the trough end and the flange bearing however can be mounted independently for use with a shelf type trough end. The housing incorporates a wide opening at the top to facilitate waste repacking along with strategic holes for oiling. They simply but effectively isolate the bearing from the trough end and potential material carry through around the shaft.
Plate Seal: Plate type seals are a simple, economical yet effective device which can be bolted between the trough end and flange bearing or used in conjunction with a shelf type trough end. Standard units incorporate a braided packing material that is compressed around the conveyor shaft when the seal is tightened in position to the trough end, however can also be supplied with a lip type seal if required.
Split Gland Seal: Split gland seals use a braided packing material which is compressed between a split adjustable housing to facilitate packing replacement and regulate the compression applied to the packing. They can be mounted either inside or outside the trough and are generally used in conjunction with a shelf type trough end.
Packed Gland Seal: The packed gland seal is used for severe applications that require effective sealing under all conditions. They can be used under both positive and negative pressure and can seal the trough either internally or externally. A braided packing media is compressed around the shaft by two compression bolts which can be used in conjunction with lantern rings and/or grease fittings depending on the application. Due to their configuration they can only be used in conjunction with a shelf type trough
end.

TROUGHS
Formed Flange Troughs: Formed flange troughs are the most commonly utilized type of U-Trough. The top flange is formed from the same steel as the trough thereby providing rigid onepiece housing section. The end flanges are jig welded in special positioning machinery for perfect alignment with the other sections.
Angle Flange Troughs: Angle flange troughs are fabricated using a heavy structural steel angle welded flush with the top of the trough edge. The welds are intermittent however can be continuous seam welds in the event that dust tight construction is required. The end flanges are jig welded in special positioning machinery for perfect alignment with other sections.
Channel Troughs: Channel troughs are commonly utilized for conveyors having long distances between conveyor supports. The trough sides are fabricated of structural steel channels that impart great rigidity to the trough. A contoured section is bolted or clamped in position. Troughs of this type are useful for abrasive applications that require frequent replacement of the lower trough sec-
tion. Drop Bottom Troughs:
Drop bottom troughs are used in applications where quick convenient access to the conveyor interior is required. The bottom trough consists of rigid upper side channels to which a lower contoured section is attached. One side of the lower contoured section is hinged while the other is attached using spring clamps or other quick opening clamps. Flanged Tubular Troughs: Tubular housings are inherently dust and weather tight. They are most often used when full cross sectional loads must be maintained such as in steep angle conveying. The trough section consists of two semi-circular halves bolted together along the flanges to form a tubular housing. Solid Tubular Troughs: The solid tubular housing maintains all the characteristics of the formed tubular housing with the exception that it is rolled from a single plate and continuously welded at the seam for dust and weather tightness.

~ r~
Formed Flange Rectangular Troughs: Formed flange rectangular troughs are formed from a single plate and are commonly used for highly abrasive applications. The material builds up to form its own trough bottom thl.Js preventing direct abrasion against the trough wall.
Angle Flange Rectangular Troughs: Angle flange rectangular troughs are identical to the formed flange type with the exception that the flange consists of a heavy structural steel angle welded flush with the top of the trough edge. The welds are intermittent however can be continuous seam welds in the event that dust tightness is required.
Flared Troughs: Flared troughs are primarily used to handle sticky or slightly viscous materials and are used in conjunction with ribbon conveyors. The flared trough sides improve the feeding and conveying action in such cases. The flanges are formed from the same plate as the trough and the end flanges are jig welded to ensure perfect alignment.
End Flanges: Trough end flanges are cold formed on special machinery and jig punched to assure dimensional accuracy in order that trough sections will align perfectly.
Trough ,
Saddles
& Support
Feet:
Trough saddles are used to support the trough at intermediate points between trough flanges and are normally welded directly to the trough. Support feet on the other hand are bolted to the end flange and are used to support the trough sections.

ENGINEERING II~FORMATION ENGLISH SYSTEM Long Measure 1 mile = 1760 yards = 5280 feet. 1 yard = 3 feet = 36 inches. 1 foot = 12 inches. Surveyor's Measure 1 mile = 8 furlongs = 80 chains. 1 furlong = 10 chains = 220 yards. 1 chain = 4 rods = 22 yards = 66 feet = 100 links 1 link = 7.92 inches. Square Measure 1 square mile = 640 acres = 6400 chains. 1 acre = 10 square chains = 4840 square yards = 43,560 square feet. 1 square chain = 16 square rods = 484 square yards = 4356 square feet. 1 square rod = 30.25 square yards = 272.25 square feet = 625 square links. 1 square yard = 9 square feet. 1 square foot = 144 square inches. An acre is equal to a square, the side of which is 208.7 feet. Dry Measure 1 bushel (U.S. or Winchester struck bushel) = 1.2445 cubic foot = 2150.42 cubic inches. 1 bushel = 4 pecks = 32 quarts = 64 pints. 1 peck = 8 quarts = 16 pints. 1 quart = 2 pints. 1 heaped bushel = 1'/4 struck bushel. 1 cubic foot = 0.8036 struck bushel. 1 British Imperial bushel = 8 Imperial gallons = 1.2837 cubic foot = 2218.19 cubic inches. Liquid Measure 1 U.S. gallon = 0.1337 cubic foot = 231 cubic inches = 4 quarts = 8 pints. 1 quart = 2 pints = 8 gills. 1 pint = 4 gills. 1 British Imperial gallon = 1.2003 U.S. gallon = 277.27 cubic inches. 1 cubic foot = 7.48 U.S. gallons. Circular and Angular Measure 60 secondes (") = 1 minute ('). 60 minutes = 1 degree (O). 360 degrees = 1 circumference (C). 57.3 degrees = 1 radian. 21T radians = 1 circumference (C). Specific Gravity The specific gravity of a substance is its weight as compared with the weight of an equal bulk of pure water. For making specific gravity determinations the temperature of the water is usually taken at 62° F. when 1 cubic foot of water weighs 62.355Ibs. Water is at its greatest density at 39.2°F. or 4° Centigrade. Temperature The following equation will be found convenient for transforming temperature from one system to another: Let F = degrees Fahrenheit; C = degrees Centigrade; R = degrees Reamur. ~ = -..f.- = -B180 100 80

Weight
or long ton = 2240 pounds. short ton = 2000 pounds. = 16 onces = 7000 grains. = 16 drams = 437.5 grains. Measures
of Pressure
1 pound per square inch = 144 pounds per square foot = 0.068 atmosphere = 2.042 inches of mercury at 62 degrees F. = 27.7 inches of V"!'ater at 62 degrees F. = 2.31 feet of water at 62 degrees F. 1 atmosphere = 30 inches of mercury at 62 degrees F. = 14.7 pounds per square inch = 2116.3 pounds per square foot = 33.95 feet of water at 62 degrees F. 1 foot of water at 62 degrees F. = 62.355 pounds per square foot = 0.433 pound per square inch. 1 inch of mercury at 62 degrees F. = 1.132 foot of water = 13.58 inches of water = 0.491 pound per square inch. Column of water 12 inches high; 1 inch diameter = .341 Ibs. Cubic Measure 1 cubic 1 cubic
yard = 27 cubic feet. foot = 1728 cubic inches.
The following measures are also used for wood and masonry: 1 cord of wood = 4 x 4 x 8 feet = 128 cubic feet. 1 perch of masonry = 16V2 x 1 V2 X 1 foot = 243/4 cubic
feet.
Shipping Measure For measuring entire internal capacity of a vessel: 1 register ton = 100 cubic feet. For measurement of cargo: 1 U.S. shipping ton = 40 cubic feet = 32.143 U.S bushels = 31.16 Imperial bushels. British shipping ton = 42 cubic feet = 33.75 U.S. bushels = 32.72 Imperial bushels. Troy Weight, Used for Weighing Gold and Silver 1 pound = 12 ounces = 5760 grains. 1 ounce = 20 pennyweights = 480 grains. 1 pennyweight = 24 grains. 1 carat (used in weighing diamonds) = 3.086 grains. 1 grain Troy = 1 grain avoirdupois
= 1 grain
apothecaries' weight. Measure Used for Diameters and Areas of Electric Wires 1 circular inch = area of circle 1 inch in diameter = 0.7854 square inch. 1 circular inch = 1,000,000 circular mils. 1 square inch = 1.2732 circular inch = 1,273,239 circular mils. A circular mil is the area of a circle 0.001 inch in diameter. Board Measure One foot board measure is a piece of wood 12 inches square by 1 inch thick, or 144 cubic inches. 1 cubic foot therefore equals 12 feet board measure. 93
