PP textile belts POLYAMID POLY AMIDEE / POLY POLYAMI AMIDE DE E C N A T S I S E R N O I S A R B A

These PP textile belts are generally used in extraction and transformation industries for conveying bulk material of large grain size at temperatures between -25°C and +60°C.

Areas of application

• Open-pit coal mines (conveying of overburden, coal and aggregates) • Open-pit mineral mines (lime, phosphates phosphates,, various ores) • Treatment of minerals • Iron and steel industries • Cement works (quarry materials and transformation) • Paper mills • Port installations • Public works • Agriculture • Sugar factories • Thermal power plants • Quarries and sand pits

Top cover Our PP textile belt consists of rubber covers and moulded edges and a textile carcass. The carcass has a multiply structure comprising 2 to 5 plies of PP (polyamide warp and weft) synthetic fabric. A layer of skim gum covers each ply.

Textile carcass Bottom cover

The covers protect the carcass against damage, adverse weather conditions and biological and chemical aggressions. The role of the carcass is to transmit the longitudinal forces and absorb the dynamic forces generated by the falling and conveying of the material. These PP textile belts are produced with cover grades W, X, Y and Z complying with standard DIN 22102 or antiabrasive cover grade D.

METALCORD 2 WEFTS E C N A T S I S E R N O I S A R B A

SEMPERTRANS ® offers you an INCOMPARABLE and UNRIVALLED STRUCTURE: THE METALCORD RANGE More than 40 years of know-how

METALCORD belts are manufactured with two types of

We guarantee excellent rubber penetration and high adhesion values. Our open type cord design, our expertise in chemical adhesion between cords and rubber and our 40-bar vulcanisation process process give the belt very high cord adhesion.

carcass (warp cords and weft cords): - Carcass with elastic M warp cords (4x7 construction), strong impact resistance, particularly suitable for: • conveyors with small pulley diameters • curved conveyors with small radii • severe conditions of use • frequent stopping and starting

Only the METALCORD belt has its own carcass, with 3 layers of metal cords (cords of variable elasticity). This type of construction presents various advantages. These include: • excellent cord/rubber adhesion • resistance to repeated shocks • resistance to penetration • ability to eject foreign bodies • limiting of longitudinal cuts and tears • possibility of total wear of covers • aptitude for winding on small pulley diameters • aptitude for accepting small convex radii of curvature • good efficiency at joint • possibility of fastener jointing • easy emergency repairs

- Carcass with reduced-elasticity E warp cords (7x7 construction), high breaking strength, particularly suitable for applications with conveyors with large centre distances. Our weft cords are specially designed (ten times more elastic than the warp cords) and enable very good troughing whatever the width of the belt. Example: 35° trough, width 800 mm, type 2250 N/mm. - Belt complying with standard EN ISO 15236

METALCORD

ADVANTAGES Usually, all metal belts have a single layer of cords in the warp direction, but only METALCORD has its own carcass with three layers of rubber-core impregnated metal cords (cords of variable elasticity). This type of construction presents various advantages. These include: OUR PERFORMANCES • excellent cord/rubber adhesion • resistance to repeated shocks • resistance to penetration • ability to eject foreign bodies • limiting of longitudinal cuts and tears • possibility of total wear of covers • aptitude for winding on small pulley diameters • aptitude for accepting small convex radii of curvature • good efficiency at joint • possibility of stapling

YOUR INTERESTS • long belt service life • saving on maintenance • better stability • safe use • quick repair • increased productivity

SHOCK ENERGY (in Joules) This criteria is always very difficult to evaluate, but the values shown below can be considered to be indicative.

METALTRANS 1 WEFT SEMPERTRANS ® offers you its METALTRANS range E C N A T S I S E R N O I S A R B A

The METALTRANS belt consists of an assembly of two layers of rubber-core impregnated cords. Genuine carcass consisting of: • one layer of cords in the warp direction • one layer of cords in the weft direction (instead of two for the METALCORD belt) Our METALTRANS belt is constructed with cords equally tensed individually, just like the METALCORD belt. Each layer of cords, warp and weft, is separated by a layer of rubber to avoid any risk of fatigue corrosion. Belt complying with standard EN ISO 15236.

CONSTRUCTION OF BELTS WITH TRANSVERSE REINFORCEMENTS The carcass is composed of warp cords with low elongation (elongation under reference load 0.2 – 0.3%). Their number and diameter depend on the breaking strength of the belt. The transverse reinforcements consist: - either of specific transverse metal cords with very high elasticity, - or polyamide fabric. These transverse reinforcements can be included in the carcass, in which case they are called the weft. These transverse reinforcements can be included in the thickness of the cover cover,, in which case they are called the breaker. breaker.

Covers: excellent resistance to abrasion, ageing and light. Bonder rubber: Adhesion to galvanised cords and to covers: excellent rubber penetration, high shear modulus, resistance to revulcanisation and ageing. Transverse reinforcement: depending on the application, with or without transverse textile or metal breaker /weft.

The standard cords are hot-galvanised and have diameters of 3.7 to 11.2 mm and 7x7 or 7x19 constructions depending on the diameter (other constructions are possible). Brass-plated cords can be used. The construction of the cords enables good penetration and distribution of the rubber. Owing to an efficient chemical process, we obtain excellent rubber-metal adhesion. This chemical adhesion between cords and rubber and the construction of the cords guarantee excellent holding power which is in all cases greater than that demanded by the standards. The good penetration of the rubber and the good adhesion of each cord ensure that Sempercord belts have an exceptional service life.

Cord construction

The abrasion index, breaking strength and breaking elongation values of the covers depend on the grade of the cover mixtures chosen (X, Y, W, etc.).

TRANSLEV EDG S ELEVATOR BELTS WITH JGS COVER The TRANSLEV structure consists of three or four plies of woven fabrics (polyester warp/polyamide weft) with a fireproof rubber interface.

The JGS cover ensures: • Resistance to vegetable and animal oils • Flame resistance as per standard ISO 340, NF EN 20340, EN 20340 and DIN EN 20340 grade S • Anti-static quality as per standard ISO 284, EN 20284, EN 20284 NF EN 20284 and DIN EN 20284 • Complying with ministerial order no. ATEP 987 0265 A of 29/07/98

The JGS cover has been specially developed to answer the two major problems involved in handling of cereals: • expansion in contact with fatty substances (maize, peanut, sunflower, etc.) • risk of explosion/p explosion/propagation ropagation of fire With regard to this, our TRANSLEV EDGS range answers these two problems since it complies with the fire-proofing standards designated above and presents good resistance to expansion in contact with oils and greases of vegetable and animal origin. These EDG elevator belts with JGS cover can also be used in areas presenting risks of explosion.


This EDGS range with JGS cover is manufactured in grade S (as defined in ISO 340, NF EN 20340, DIN EN 20340 and EN 20340) as regards fireproofing, i.e. with inflammable cover and carcass . Thus, even when the cover is torn off, the t he belt remains fireproof and still meets the criteria of the standard.

TRANSPROFIL STEEP GRADIENT CHEVRONS TRANSPROFIL belts have 15 mm or 25 mm high chevrons

AREAS OF APPLICATION • Mines • Cement works • Cattle feed • Cereal silos • Port installations • Chemical fertilizers • Sugar factories • Quarries and sand pits

moulded and directly integrated in the cover of the conveyor belt. These profiles are produced in a very high quality (grade D) anti-abrasive cover.

ADDITIONAL INFORMATION TRANSPROFIL belts have 15 mm or 25 mm high chevrons moulded and directly integrated in the cover of the conveyor belt. These profiles are produced in a very high quality antiabrasive cover c over..

Depending on the width of the belt and the type of material conveyed, we will advise you on the most appropriate chevron height (15 mm high chevrons or 25 mm high chevrons).

S N O I T A C I L P P A D E S I L A I C E P S

The TRANSPROFIL is a chevron belt specially designed to meet the specific requirements of an increase in the angle of inclination of the conveyor. It will be used in cases in which a conventional conveyor belt is incapable of retaining the materials conveyed.

In very many cases, the angle of inclination of the belt must not exceed 20°. TRANSPROFIL belts provide an answer to this drawback. If the angle of inclination has to exceed 20°, TRANSPROFIL belts will allow you to convey your materials at a greater incline (max. 30° or 40° depending on the case) while at the same time allowing you to save space in your installations.

TRANSLEV ELEVATOR BELT The LPM and LPMWH ranges represent a unique technical solution in the top range elevator belt field. Consisting of a layer of longitudinal cords inserted between two layers of transverse cords, these belts provide working safety in large elevators which is unrivalled in the market.

The technological lead of our metal carcass belt compared to the belts available on the market lies in the fact that it consists of special cords enabling: • better bucket attachment owing to a layer of high-density reduced-diameter longitudinal cords inserted between two layers of transverse cords. • a value for cord adhesion in the coating which is far superior in cumulative value to the values which can be obtained using cords of higher unit diameter diameter.. This is essential for hot product belts in which the cord adhesion drops considerably with the raising of the temperature. • minimal diameters for winding of the belt on the pulleys owing to the small diameters of the longitudinal cords. • excellent rubber penetration and high cable adhesion values owing to the open type cord design. This performance is further enhanced by expertise in chemical adhesion between cords and rubber and by vulcanisation at 40 bar.

Because of their metal carcass, the TRANSLEV LPM and LPMWH ranges allow: • high working tensions • low tension travels • high bucket attachment values values (triple layer of of two-way cords) • high heat resistance (LPMWH)

TRANSLEV LPM/LPMWH

The LPM range (SBR cover grade) is suitable for material temperatures of up to 60°C. The LPMWH range is designed for handled material temperatures of up to 130°C.


The LPWH range is a two-ply belt with a textile carcass (polyester warp, polyamide weft) inserted between two transverse reinforcements and cover. This belt (butyl cover grade) is designed for handled material temperatures of up to 130°C. It also presents remarkable bucket attachment values owing to its multi-layer structure and these transverse reinforcements.

AUTOSTABLE INSTANTANEOUS SELF-CENTRING


The patented construction principle of the AUTOSTABLE belt ensures instantaneous self-centring. This self-centring effect without the use of accessories or modifications of the installation offers numerous advantages: • Stability of the b elt along its whole length, thus no risk of offcentring and therefore no deterioration of the moulded edges. • Elimination of systematic pinching, hence less wear and lower friction (reduction of power consumed). • Increase in output owing to stabilisation of the vein and the slope of the product and the possibility of increasing the trough angle.





• Reversible installation installationss • Installations with poorly centred load (e.g. bucket wheel) • Port installatio installations ns (ores, coal, phosphates) • Mines / Iron and Steel Industry (ores, cokes, added materials) • Thermal power plants (coal, ash) • Cement works (quarry materials, added materials, cold clinker) • Quarries / Sand pits (grain size < 400 mm) • Paper mills (wood, edgings) • Fertiliser factories / Chemical plants (non chemically aggressive materials) • Salt marshes / salt works • Sugar factories (sugar beet, cane, sugar beet chips) • Glassworks (raw materials, cullet, recycling)

AUTOSTABLE

INSTANTANEOUS SELF-CENTRING One of the main problems encountered in the use of conveyor belts is off-centring. This phenomenon resulting from various causes leads to clogging of installations, reductions in output, deterioration of the moulded edges and a noticeable shortening of the service life of the belt itself.

The patented construction principle of the AUTOSTABLE METAL belt is based on the qualities of METALCORD belts. In particular, this belt offers the qualities and performance associated with the use of cords of various elasticities. Its originality lies in the incorporation of a double metal stiffening layer. One narrower layer is centred on the centre line of the belt, creating a “beam effect” in the central part. The difference in flexibility between this central area and the side areas, which are more flexible in comparison, favours the self-centring of the belt. As the rigid central part cannot adapt to the angle formed by the idler rollers, the belt tends to return to its it s natural trough, thus favouring its stability along its whole length.

1 – Top cover 2 – Bottom cover 3 – Idler roller (length of generatrix to be specified at time or order) 4 – Variable weft (of a width roughly equal to the generatrix of the centre roller) 5 – Normal weft 6 – Warp 7 - Side idler rollers

• Self-centring

The AUTOSTABLE AUTOSTABLE belt centres itself of its own accord on the conveyor. • Increased service life

Reduction of the risks of off-centring and therefore of deterioration of the moulded edges. Elimination of pinching and therefore less wear and lower friction.

PIPETRANS/PIPECORD SOLUTIONS FOR TUBULAR CONVEYORS Based on an original idea combining know-how and technical innovation, this handling system makes it possible not only to preserve the environment but also to protect the product conveyed.

The PIPETRANS / PIPECORD range is renowned for providing an ideal solution for this type of handling. The PIPETRANS range consists of a specially-designed twoply or multiply structure of woven fabrics (polyester warp/polyamide weft) with cutting of plies in the longitudinal direction to enable overlaping of the edges of the tube. The PIPECORD range has a carcass consisting of: • in warp: special high-elasticity cords alternately stranded right and left to counterbalance the twist of the tube • in wefts: special high-elasticity cords of a width designed to provide the appropriate transverse rigidity and enable the overlaping of the edges. It should be noted that the design of the weft is important as it must ensure the maintaining of the tubular shape of the belt in all cases of stress applied to it, particularly on curves, and must prevent the crushing of the belt.

The tubular conveyor can be used to convey all types of products in bulk, from the finest to the coarsest, with a tube diameter two and a half times greater than the maximum grain size. The types of materials which can be conveyed by the tubular conveyor are extremely varied and currently include various sorts of materials of a powdery nature (cements, ash, fly ash, etc.) or otherwise (coal, coke, ore, limestone, gypsum, sludge, fertiliser, sugar, wood chips, etc.).

SQUAREBELT SQUARE SECTION TUBULAR CONVEYOR The know-how and technical innovation of SEMPERTRANS ® has resulted in the development of a new handling system: the SQUAREBELT. Combining the technical characteristics of the AUTOSTABLE belt for its construction and of the PIPE CONVEYOR for its use, the SQUAREBELT provides an optimum solution to problems of handling bulk products without pollution of the outside environment while at the same time protecting the product conveyed, and offers a unique advantage compared to a conventional pipe conveyor by preventing twisting of the belt, particularly in curved conveyors.

ADVANTAGES OF THE SQUAREBELT • Environmental protection: the material is totally isolated from the outside environment • Perfect belt alignment: avoids any risk of twisting of the belt • Vertical and horizontal curves: the use of elastic cords allows radii of curvature in vertical and horizontal planes • Roller spacing: because of its inertia, the square cross section allows considerable spacing of the stations

The materials can be conveyed on both strands of the belt. At the loading and tipping points, the SQUARE CONVEYOR is opened and closed in the form of a standard trough to pass flat over the pulleys like a conventional conveyor belt.








60

SQUAREBELT

CONSTRUCTION of SQUARE BELT Example of square construction

The SQUARE BELT uses 3 stiffeners with 2 flexible edges to form a square section which contains the material to be conveyed. This revolutionary construction is protected by a patent. The carrier strand and the return strand are supported and guided identically by four rollers, 2 vertical ver tical and 2 horizontal. AVAILABILITY OF THE SYSTEM Although the SQUARE CONVEYOR and the SQUARE BELT are already available on the market, this system is still undergoing development and a test programme to validate the limits of use. Please consult our technical t echnical departments.

TRANSRIGID STUDIED RIGIDITY The TRANSRIGID range is composed of belts with high transverse rigidity for flat use. They mainly serve as a support for corrugated flanged edges and ribs, to produce conveyors with steep gradients and specific geometries. XST2 belts are fitted in installations presenting harsh working conditions with numerous changes of gradient. XMM belts enable the quality of the metal warp to be combined with particularly rigid wefts. These belts are intended for installations in which the working conditions are harshest and are suitable for “silo covering” applications.

AREAS OF APPLICATION - Port installations - Quarries - Silos - Mines - etc.

TRANSRIGID belts can be equipped with all standard types of edges and ribs on the market. SEMPERTRANS® can

supply you with equipped belts on request.

• XST2: two or three woven plies (polyester warp / polyamide weft) between two layers of rubber core impregnated metal cords of specially designed rigidities. • XMM: assembly consisting of three layers of rubber core impregnated metal cords. - Warp direction: one layer of cords of appropriate elasticity - Warp direction: two layers of cords of specially designed rigidity located on either side of the warp.

MINIMUM DIAMETER OF PULLEYS The minimum diameters of the pulleys of belt conveyors are determined by taking into account: the construction of the belt, its weight and the type of splicing. Three types of pulleys are distinguished: • Tension pulleys and other pulleys located in the area of highest tension of the belt • Tail pulleys and other pulleys located in the area of lowest tension of the belt • Snub or bend pulleys which do not change the direction of the belt by more than 30°. The minimum diameter of a pulley also varies according to the tension in the belt. For high types, do not forget that the weaker the surface pressure on the pulley, the better the (belt/pulley) adhesion coefficient will be Pulley diameters greater than the recommended minimum diameters will increase the service life of the belt. For large cover thicknesses, it is recommended to increase the diameters of the pulleys. For belts not indicated in this table, please consult our technical departments.

TENSION TRAVEL NECESSARY FOR BELTS The adjustment of the tension travel depends on: load

• The centre distance of the conveyor and its working tension • The conveyor starting and stopping system. • The position of the tension system • The nature of the carcass of the belt

d a o l g n i k a e r b t l e b

The elongation of a belt is broken down into two parts: the permanent elongation and the elastic elongation. In certain cases it is possible to reduce the tension travel by complying with certain procedures • Either during manufacturing • Or during placing of the belt in endless configuration on the operating site. Consult our technical departments.


Permanent Elastic elongation elongation Total elongation

For textile belts, the permanent elongation and the elastic elongation are divided into two roughly equal parts for weak types; the permanent elongation increases with the type of belt because of the greater crimping of the constituent fabrics. For metal belts the elongation consists of approximately 1/5th permanent elongation and 4/5ths elastic elongation. Tension travel to be provided for according to the belt family (see table on following page). On conveyors with small centre distances, it is necessary to allow a minimum tension travel in order to be able to place the belt in endless configuration.

RADIUS OF CURVATURE RADIUS WITH CENTRE ABOVE (CONCAVE)

RADIUS WITH CENTRE BELOW (CONVEX) The approximate values which can be used to determine the radius of curvature are indicated below. Note 1: For convex radius (centre below), it is recommended to reduce the trough angle by 5 to 10° and eliminate any pinching of the rollers in this area. Note 2: For concave radius (centre above), it is generally the empty belt non-lifting conditions which determine the minimum radius values. Textile belts:

TURNOVER

Free turnover (180 degrees): the belt is guided between two vertical pulleys Forced turnover: for belts of width less than or equal to 1200 mm, the belt is guided by supports. For widths greater than 1200 mm, all along the turnover the belt must be guided and supported by special rollers.
