A belt conveyor pulley is a device which is used to change the direction of the belt and drive & tension the belt. It is an important part of belt conveyor. What are the types of belt conveyor pulley?
We can classify conveyor pulleys into drive pulley, tension pulley, motorized pulley, snub pulley, wing pulley and bend pulley. The surface of conveyor pulley can be smooth, rubber-coated and cast rubber.

The electric pulley is a driving device that integrates the roller body and the transmission device, and at the same time plays the role of driving and changing the winding direction of the tape. If you get a conveyor pulley that has an internal motor, you can both improve the efficiency of your operations and save some space. With a motorized pulley, your conveyor system will stay durable and compact. This is often a safer option than a traditional hydraulic conveyor system.
The driving pulley is the main component that transmits traction to the conveyor belt. The surface of drive pulley is often coated with chevron and diamond. Only enough friction between belt and pulley can drive the belt conveyor. A drive pulley is always single-sided or double-sided, meaning it has one or two drives. Depending on the size of the conveyor system, one or more drive pulleys are used at different positions in the system.

The function of the bend pulley is to change the winding direction of the belt so that the belt forms a closed loop. The bend pulley can be used as the tail roller of the conveyor to form the tension roller of the tensioning device and cause the belt to be redirected at different angles. The design of a bend pulley is similar to a return pulley, but the diameter is often smaller. The pulley design is often lighter, as the smaller length of the tensioned conveyor belt causes less tension.
A tension pulley is actually a return pulley which is used to tension the conveyor belt. Tensioning the belt leads to high forces on the pulley. Therefore, the tension pulley is often a solid type of pulley. The tension pulley can also be used as a return pulley at the tail of the belt, and as a tension pulley at any other position in the lower part of the belt. In this case, the preferred position of the tension pulley is as close as possible to the drive pulley where the tensioning forces required for the belt are lowest.
It often works with a drive pulley and is used to enlarge the touching areas of belt and drive pulley. The snub pulley can increase the friction between belt and driving pulley. The snub pulley is therefore particularly suitable for conveyor systems that require very high drive power or systems in highly contaminated environments.
Wing Pulley
The wing pulley can clear the material on the return belt. Since it is constantly cleaning itself, a wing pulley has good traction. That means this is a very efficient choice when it comes to pulleys. You can find many different kinds of wing pulleys, like spiral wing pulleys, heavy-duty wing pulleys, and herringbone wing pulleys.
The magnetic drum pulley is mainly used in the beneficiation production line. The magnetic force of the drum is used for the separation of magnetic ore or the removal of iron for coal burning, foundry sand, refractory materials and other industries. Magnetic pulleys are constructed of quality steel, strong permanent magnets enclosed by stainless steel by welding. They are designed to remove large and small ferrous debris from product streams in belt conveyor systems. Magnetic pulley separators are typically placed at the head of conveyer belt.
