Head/Drive Pulley is located at the discharge terminus of the conveyor. 2. Drive pulley provides the driving force for the conveyor. In order to increase pulley life and traction, it often has a larger diameter than other pulleys.3. We can supply pulleys with hot vulcanized rubber lagging, plain or grooved, as required by client. Different patterns of grooving such as herringbone or diamond can be provided to increase tractive friction under dirty or wet conditions. Diamond grooves have the advantage of being installed in any orientation, regardless of belt direction.Specification of Drive Head Pulley DrumBelt Width500-2800mm (19-110 inch)Pulley Length500-3500mm (19-138 inch)Diameter200-1800mm (8-70 inch)StandardISO9001:2008, CEMA, DIN, TUV, JIS, AS/NS, etc.Working LifeMore than 30,000 hours.SurfaceFlat Rubber Lagged, Ceramic Lagged, Diamond Rubber Lagged, etc.Main MaterialCarbon SteelLength of conveyor drive pulley depends on the width of conveyor Belt. You can get drive pulleys with hot & cold vulcanized rubber lagging, plain or grooved, as required by client.Bend Pulley Introduction:1. The bend pulley is used for changing the direction of the belt.2. The bend pulley is usually installed at the tail part or the vertical take-up equipment part when the belt direction need to 180°bending. It will be installed above the take-up equipment part while 90°bending.3. The pulley, which is used for extending the contact surface, is usually used for below or equal to 45 degree bending.4. The surface treatment of the bend pulley can be smooth steel and flat rubber lagging.

You can get drive pulleys with hot vulcanized rubber lagging, plain or grooved, as required by client.Snub PulleySnub pulley is used to achieve higher angle of wrap on the drive pulley thereby increasing the traction. It also reduces the belt tension maximizing the life of the conveyor component.It is mounted close to the drive pulley on the return side of the belt.Specification of Snub Pulley:ItemsContentBelt Width500-2800mm (19-110 inch)Pulley Length500-3200mm (19-126 inch)Diameter200-1800mm (8-70 inch)StandardISO9001:2008, CEMA, DIN, TUV, etc.Working LifeMore than 30,000 hours.SurfaceFlat Rubber Lagged, Ceramic Lagged, Diamond Rubber Lagged, etc.Main MaterialCarbon SteelLength of conveyor Snubpulley depends on the width of conveyor Belt. You can get Snubpulleys with hot vulcanized rubber lagging, plain or grooved, as required by client.Take Up Pulley The take up pulley will ensure adequate tension of the belt leaving the drive pulley so as to avoid any slippage of the belt, ensure proper belt tension at the loading and other points along the conveyor, compensate for changes in belt length due to elongation, and provide extra length of belt when necessary for splicing purpose.Specification of take up pulley drum:Belt Width500-2800mm(19-110 inch)Pulley Length500-3200mm(19-126 inch)Diameter200-1800mm(8-70 inch)StandardISO9001:2008, CEMA, DIN, TUV, etc.Working LifeMore than 30,000 hours.SurfaceFlat Rubber Lagged, Ceramic Lagged, Diamond Rubber Lagged, etc.Main MaterialCarbon SteelThe components of a pulley drum include the following:Drum or ShellThe drum is the portion of the pulley in direct contact with the belt. The shell is fabricated from either a rolled sheet of steel or from hollow steel tubing.The shell has a specific 'face' width and diameter which is determined by the width of the belting and the type and rating of the belt to be used on the conveyor.Diaphragm PlatesThe diaphragm or end plates of a pulley are circular discs which are fabricated from thick steel plate and which are welded into the shell at each end, to strengthen the drum.The end plates are bored in their centre to accommodate the pulley shaft and the hubs for the pulley locking elements.ShaftThe shaft is designed to accommodate all the applied forces from the belt and / or the drive unit, with minimum deflection.The shaft is located and locked to the hubs of the end discs by means of a locking elements.The shaft is supported on both ends by bearings which are housed in plummer blocks, to support the shaft and pulley assembly on the conveyor structure.Shafts often comprise different diameters along their length due to the bending moments and resultant deflection limitations. The diameter of the shaft at the landings for the bearings may be smaller to satisfy the necessary bearing diameter which is more cost-effective (smaller).Similarly in the case of a drive shaft, the drive attachment, may be different to the other diameters along the shaft and hence pulley shafts are often stepped.Locking ElementsThese are high-precision manufactured items which are fitted over the shaft and into the pulley hubs. The locking elements attach the pulley firmly to the shaft via the end plates.Locking elements work on the friction-grip principle whereby the element is able to be fastened to the shaft and hub simultaneously and concentrically, by tightening a series of screws around the locking element.HubsThe hubs are fabricated and machined housings which are welded into the end plates. The hubs are sized according to the size of the pulley, the diameter of the shaft and the size of the locking element which is required for the specific duty.LaggingIt is sometimes necessary or desirable to improve the friction between the conveyor belt and the pulley in order to improve the torque that can be transmitted through a drive pulley.Improved traction over a pulley also assists with the training of the belt.In such cases pulley drum surfaces are 'lagged' or covered in a rubberized material. This cover is usually 8 mm to 12 mm thick and can be plain or have a grooved pattern. The rubber lagging is vulcanized to the pulley shell to ensure that it remains attached under adverse operating conditions.Bearing AssembliesBearings support the rotating shaft and hence the pulley. The bearings are housed in 'plummer blocks' which enable the mass of the pulley assembly plus the belt tension forces to be transmitted to the pulley supporting structure.Plummer blocks are often bolted to 'sole plates' which are welded to the structure.The sole plates incorporate jacking screws to enable the pulley to be correctly and relatively easily aligned.Several types of bearing housing, seals and end disc:Pulley Drum Warehouse and package:Pulley Drums:Company profile: Hengshui Xinrisheng Intelligent Conveying System Co.,Ltd (abbreviated as Xinrisheng Intelligent) is the High-end Conveying Equipment brand , with excellent technical team and in house intellectual property & national patents,developing intelligent conveying machinery.
