Heavy-Duty Feeders

Syntron® Heavy-Duty Vibrating Feeders Electromagnetic Feeder Syntron® Vibrating Feeders for heavy industry are ideal for feeding a wide variety of bulk materials from storage piles, hoppers, bins and silos. Rugged and dependable, Syntron heavy-duty feeders are backed by years of serviceproven performance in the mining, aggregates, glass, cement, chemical, wood products and steel industries. Syntron Vibrating Feeders are designed to increase bulk handling productivity with high, controlled feed rates to improve cost-per-ton efficiency. Electromagnetic and electromechanical models are available. With capacity ranges from 25 to 4,000 tons per hour, these feeders are ideally suited for high-tonnage feeding. Feeder selection should include consideration of production requirements, material characteristics, and operating environment.

Syntron ® F-Series Electromagnetic Feeder

Electromechanical Feeders

Syntron Vibrating Feeders are sub-resonant tuned, two-mass, spring-connected systems. These features enable Syntron feeders to work consistently under material damping and other varying headload conditions with negligible changes in trough stroke. Sub-resonant tuning maintains stroke consistency and speed stability, thus delivering higher capacities at controlled feed rates. Precise, sub-resonant tuning is a key characteristic of both types of Syntron vibrating feeders. Electromagnetic models are tuned through careful calculation of the number and thickness of the special leaf springs required to accomplish the desired tuning ratio. Electromechanical models are tuned by adjusting the operating speed to obtain the exact tuning ratio. Because subresonant tuning is so critical to feeder performance, a detailed explanation is provided for electromagnetic feeders on page 6 and for electromechanical feeders on page 15.

Syntron ® MF Electromechanical Feeder

Dependable, flexible control sets Syntron vibrating feeders apart from other feeding and conveying machinery. Material feed rates are controlled and easily adjusted with Syntron solid-state controls; a wide range of standard and special models is available. Control devices can also be supplied for integration into systems that use external signals from automatic sensing devices. In addition, control arrangements are available for selecting and sequencing a group of feeders. Syntron® RF Electromechanical Feeder

Syntron® Electromagnetic Feeders

Syntron® Heavy-Duty Electromagnetic Feeders Bulk material feeding with full-range control. Syntron® Heavy-Duty Electromagnetic Feeders come in ten different models with capacities ranging from 25 to 1600 tons per hour.* These versatile feeders are capable of handling a variety of materials from the finest powders to large, coarse particles. Syntron Electromagnetic Feeders can be supplied in various configurations including multiple- drive units and above-deck drive units. Above-deck drive units are recommended where there is insufficient space below the trough. Syntron Electromagnetic Feeders require minimal maintenance as there are no mechanical parts to wear out, such as cams, eccentrics, belts and bearings – thus eliminating the need for lubrication. All movement is confined to the heavy-duty leaf springs. Electrical components, such as the coil, will provide years of service under normal operating conditions. Dust-tight drive units are standard on all models. Dependable, flexible controls provide easily adjustable feed rates with instantaneous response. A variety of controls with special control arrangements are available. (For more information on electromagnetic feeder controls, see pages 26 - 28.)

Syntron® F-380 Electromagnetic Feeder with above-deck drive unit evenly distributes parts at a consistent rate to a heat treatment furnace.

Feeding gypsum with Syntron model F-380 Electromagnetic Feeder.

Syntron® Electromagnetic Feeders are normally installed by suspension mounting with four flexible wire rope cables. They can also be supplied for base mounting on a solid base, or with a combination of base mounting and suspension mounting.

Syntron Electromagnetic Feeders are ideal for use in a stationary operation such as a tunnel system from a surge pile. They are usually controlled from a remote point to provide the desired feed rate. In this application, a model FH-22 feeds limestone to a belt conveyor.



Syntron® Electromagnetic Feeders (cont’d.)

Sub-Resonant Tuning for Electromagnetic Feeders Low sub-resonant tuning is the key characteristic of Syntron® electromagnetic feeders, making them the most stable and consistent feeders available on the market. Feeder tuning involves adjustment of the natural frequency of the feeder in relationship to its operating frequency. If the operating frequency is greater than the natural frequency, the feeder is superresonant tuned, making it very unstable under headload. Conversely, if the natural frequency is greater than the operating frequency, the feeder is sub-resonant tuned, making it more consistent and stable under headload. Electromagnetic feeders are tuned through careful calculation of the number and thickness of the special leaf springs required to accomplish the desired tuning ratio. Regardless of manufacturer, all heavy-duty, two-mass electromagnetic vibrating feeders are subresonant tuned. For sub-resonant tuned feeders, the distance from resonance is critical to feeder performance. Most manufacturers tune their feeders closer to resonance, while Syntron electromagnetic feeders are tuned further from resonance.

6

The natural frequency of all Syntron® Heavy-Duty Electromagnetic Feeders is checked at our test stations before shipment.

Material damping and other variations in headload cause fluctuations in capacity and feed rates of all sub-resonant tuned feeders. Because Syntron electromagnetic feeders are tuned further from resonance, capacity and feed rates remain more stable and consistent even when the feeder is subjected to material damping and other variations in headload.

This is why Syntron electromagnetic Feeders are the best solution for rugged material handling applications.

Syntron® Electromagnetic Feeders (cont’d.) Electromagnetic Feeder Troughs Syntron® Electromagnetic Feeder models FH-22 through F-88 can be furnished with standard flat-bottom troughs, special flat-bottom troughs or belt-centering discharge troughs. Drive units can be positioned either above or below the trough. A below-deck drive unit is most commonly used, but above-deck drive units can be supplied for installations where there is insufficient space below the trough. However, an above-deck drive unit may reduce feeder capacity slightly.

Standard flat-bottom trough, below-deck drive unit.

Capacities for feeder models with standard troughs are based on sand weighing 100 pounds per cubic foot. Capacities vary depending on drive unit location, material characteristics, material density, trough length and width, trough liner type, feeder installation, skirt boards and hopper transitions. Several trough options are available for special applications. Syntron ® extralong feeder troughs can be supplied with either below-deck or above-deck multiple electromagnetic drive units. Extra-long feeder troughs provide many advantages in conveying materials over long distances; unlike belt conveyors, there are no idlers or pulley drive units to wear, lubricate, or replace. Long tubular troughs can convey pure, clean materials without atmospheric contamination and safely convey dusty, poisonous materials without endangering processing personnel.

Tubular trough, below-deck drive unit.

Other trough options include: • Syntron vibrating inspection tables feed material forward at a smooth, controlled rate of flow. This enables an operator to remove material that does not meet specification.

Flat bottom trough, above-deck drive unit.

• Syntron “spreader” feeders spread a wide, even layer of material with a diagonal discharge trough or diagonal-slotted trough. • Electrically heated trough liner plates minimize accumulation of damp or wet materials in feeder troughs. Available only on specially designed feeders, heated liner plates increase feeder efficiency by eliminating the downtime required to clean troughs. They are especially effective for materials with moisture contents ranging from five to fifteen percent. The electric heating element is insulated and sandwiched between two steel plates.

Multiple-Drive Unit Electromagnetic Feeders Syntron® Electromagnetic drive units can be combined to create feeders ideally suited for special applications. Multiple-drive units, positioned one behind the other, result in a long, vibrating conveyor. When an especially wide material layer is desired, multiple-drive units can be placed side by side on extra wide feeder troughs. The number of drive units required is determined by the trough width and length. Dual-twin drive units – two sets of twin drive units, one set placed behind the other – provide both increased capacity and the ability to handle exceptionally heavy loads.

Sub-resonant Tuning for Electromechanical Feeders Stroke consistency and speed stability for high-capacity feeding. Low sub-resonant tuning is the key characteristic of Syntron® electromechanical feeders, making them the most stable and consistent feeders available on the market.

Sub-Resonant Tuning for Electromechanical Feeders

Feeder tuning involves adjustment of the natural frequency of the feeder in relationship to its operating frequency. If the operating frequency is greater than the natural frequency, the feeder is superresonant tuned, making it very unstable under headload. Conversely, if the natural frequency is greater than the operating frequency, the feeder is sub-resonant tuned, making it more consistent and stable under headload. Regardless of manufacturer, all heavy-duty, two-mass electromechanical vibrating feeders are sub-resonant tuned. For subresonant tuned feeders, the distance from resonance is critical to feeder performance. Most manufacturers tune their feeders closer to resonance, while Syntron feeders are tuned further from resonance. Material damping and other variations in headload cause fluctuations in capacity and feed rates of all sub-resonant tuned feeders. Because Syntron electromechanical feeders are tuned further from resonance, capacity and feed rates remain more stable and consistent even when the feeder is subjected to material damping and other variations in headload. In addition, Syntron electromechanical feeder design incorporates internal damping, which contributes to their stability and consistency. On the comparison chart (Figure 1), curve 1 represents a typical competitive feeder in a no-load state without internal damping. Curve 2 represents a Syntron feeder in a no-load state with internal damping. Curve 3 represents a feeder with material headload and associated damping. Because Syntron feeders are tuned further from resonance and are designed with

Figure 1. Comparison of Tuning Ratios

internal damping, it is evident that the loss in relative trough stroke under headload for a Syntron feeder (Y) is negligible as compared to a substantial loss in relative trough stroke for competitive feeders (X). This is why Syntron electromechanical feeders are more consistent and stable than any other feeder, even when subjected to material damping and other variations in headload.



Syntron® RF Electromechanical Feeders

RF Medium-Duty Electromechanical Feeders These master material movers can feed it all. Syntron® RF Medium-Duty Electromechanical Vibrating Feeders meet the varying, mid-range bulk material handling needs of industry. Capable of handling a wide range of materials, these two models provide feed rate capacities from 400 to 600 tons per hour.* Syntron RF feeders are two-mass vibrating units; the trough is one mass and the exciter unit is the other. The exciter is belt-driven by a standardframe induction motor and connected to the trough with long-life polymeric shear springs. The ball bearings in the exciter unit have a minimum life expectancy of 20,000 L10 hours. Variable pitch motor sheaves provide a positive method of tuning. This Syntron design permits higher feed capacities from smaller trough sizes, enabling you to select a more economical unit to meet your capacity requirements.

Recommended Installation Recommended Designs for Hoppers and Transitions Feeder Transition Hoppers Feeder capacity depends on the design of the hopper. Material characteristics such as size distribution, shear properties and cohesiveness generally dictate the configuration of feeder transition hoppers. Material flow velocities vary, depending upon material properties, feeder stroke and operating speed. Good transition hopper design optimizes flow rate, resulting in the most economical choice of a feeder. Improperly designed transition hoppers will substantially reduce feeder capacities. Figure 1 illustrates Ideal and Acceptable Hopper designs.The Ideal Hopper with a throat (T) to gate height (H) ratio of 0.6 shows a uniform material flow pattern to the feeder trough. Material at the front and rear of the hopper moves at nearly the same velocity, and the discharge depth (d) is nearly equal to the hopper gate height. The Ideal Hopper design allows the most economical feeder to be used. The Acceptable Hopper design may require a slightly larger feeder than required for the Ideal Hopper design. This is due to the non-uniform flow pattern of material at the rear of the hopper. Material flow velocity is reduced, material depth “d” is reduced and there is a reduction in feeder capacity. A T/H ratio of 0.6 to 1.0 is generally acceptable. However, when the T/H ratio exceeds this range, the material flow patterns distort drastically and will significantly reduce capacities. T H C d

If material size is -4-in with a trough down slope of up to 10 , use 30-40 ft/min. If material size is +4-in to -12-in with a trough down slope of up to 10 , use 25-30 ft/min. If material size is +12-in with a trough down slope of up to 10 , use 20-30 ft/min.

If material size is -4-in with a trough down slope of up to 10 , use 50-60 ft/min. If material size is +4-in to -12-in with a trough down slope of up to 10 , use 45-55 ft/min. If material size is +12-in with a trough down slope of up to 10 , use 40-50 ft/min. Feeder down slope usually effects flow rate by 2% per degree. As down slope increases flow rate increases. As down slope decreases flow rate decreases.

Recommended Hopper Design and Feeder Selection Refer to Figure 2. 1. Rear wall angle steep enough to permit material flow (60˚ ± 5˚). 2. Front wall angle just enough to permit material flow (55˚ ±5˚). 3. The throat dimension “T” for random size material should be a minimum of 2 times the largest particle of material. For particles that are nearly the same size (near size), “T” should be a minimum of 4 times the largest particle size to prevent blockage at the throat opening. In all cases, the arc “A” should exceed 2 1/2 times the largest particle size. 4. Gate opening “H” must be a minimum of 2 times the largest particle of material and should increase proportionally for the desired capacity. The most economical feeder is selected when the throat dimension “T” is equal to or slightly larger than H/2. If “T” is greater than “H” the flow pattern of the material is disturbed, resulting in non-uniform flow. 5. When adjustable gates are used, the gate must be parallel to the hopper’s front wall and must be as close to the front wall as possible. The separation must not exceed 2 inches. The gate should act as an adjustable front wall. Leveling blades and down stream gates must not be used. Horizontal cut off gates should be used to perform feeder maintenance and must not be used to regulate flow. 6. The inside width of the opening “D” (between stationary skirtboards) should allow for a 1-inch clearance between the feeder trough and skirt boards and should be a minimum of 2 1/2 times the largest particle size. For near size material the width of “D” should be a minimum of 4 times the largest particle size. 7. The minimum length of the feeder is determined by projecting the angle of repose for the specific material from the gate point to the feeder pan and adding approximately 6 inches. 8. The feeder must not contact any adjacent structure but must be free to vibrate. Allowance must be made for a decrease in feeder elevation of approximately 2 inches, due to static material load. In addition, 1 inch minimum clearance at sides and 1 1/2 inches at bottom and back must be maintained in both loaded and unloaded conditions.

9. The skirts must taper in the direction of flow (diverge from conveying surface) to prevent material from jamming and causing additional problems such as spillage and build-up. Skirts must run parallel to trough sides and must be reinforced to resist bulging outward against trough.
