Pulleys

Our product range contains a wide range of Head Drive Pulleys, Tail Pulleys and Drum Pulley

Head Drive Pulleys

Head/ Drive pulley is located at the discharge end of the conveyor. It is known for providing driving force to the conveyor. May or may not be the head pulley. Usually it has a larger diameter than other pulleys in the system and is often lagged to increase traction and pulley life. The lagging on this type of pulley is usually hot vulcanized lagging with preferably diamond grooves on the face of the pulley.

Alignment of the head/ drive pulley is done keeping in view the speeds that the pulley is rotated at. Alignment is of utmost importance as to prevent the slippage of the conveyor belt from the face of the pulley. Bearing assemblies are provided with the pulley. Heavy construction reduces the likelihood of metal fatigue and pulley failure in severe applications minimizing down-time and maintenance costs. In any mineral processing plant the ore has to be transported and fed to different processing equipments, located at different points at a continuous rate. Conveyor belt helps in serving this purpose. Conveyor belts can be as short as few meters to as long as several kilometers. The Head End Pulley gives motion to the conveyor belt. The driving pulley can be at the head end or at the tail end, depending on the layout of the conveyor, space available and loading conditions. It is the head end where generally the belt discharges the carried material and return for reloading

Tail Pulleys

As the name rightly suggests a tail pulley often located immediately preceding the loading point of the conveyor near the tail side. A tail pulleyis a self driven pulley that moves in tandem with the head pulley of the conveyor driving angular momentum from it.

It is engineered to accommodate specific belt tensions for use in critical applications where down time must be minimized. Though very similar to the head end pulley of the conveying system, but the tail end pulley is not attached to a driving mechanism rather it moves with the movement of the conveyor belt which draws power from the head end pulley. The tail pulley is located at the tail end of the conveyor and it turns freely.

Drum Pulley

Tightens belt giving more surface contact between belt and pulley face. It is usually located just behind the drive pulley but there is no such rule to use it there and can be fixed also be used at where it can be used at any location. It consists of a rim shell, 2 end discs and 2 shaft locking assemblies.

Belt slippage means costly downtime. The use of a snub pulley is one solution. Mounted close to the drive pulley on the return side of the belt, the snub pulley's primary job is to increase the angle of wrap around the drive pulley, thereby increasing traction. Its secondary purpose is to reduce belt tension, which is important in maximizing the conveyor life. The specification of a snub pulley is dependent upon drive horsepower, material characteristics and environmental conditions.
