What is a conveyor pulley?
A conveyor pulley is a core component of a belt conveyor. It drives or guides the conveyor belt through rotation, and is mainly divided into drive pulleys and idler (bend) pulleys. It is widely used in ports, mines, power plants and cement plants.
How does a conveyor pulley work?
A drive pulley is rotated by a motor through a gearbox. Friction between the pulley surface and the belt transmits power to move the belt. An idler pulley changes the belt direction or increases the wrap angle.
What are the main types of conveyor pulleys?
The main types include drive pulleys, idler (bend) pulleys, snub pulleys and heavy-duty pulleys. By surface treatment, they are divided into plain pulleys and lagged pulleys, each suited to different working conditions and tension requirements.
Why is pulley lagging used?
Lagging increases the friction coefficient between the pulley and the belt, prevents slipping, reduces wear and extends the service life of both the pulley and the belt. Common lagging materials include rubber, ceramic and polyurethane.
What are the main components of a conveyor pulley?
The main components include the shell, shaft, bearing housings, hubs, lagging layer and locking device. Heavy-duty pulleys also use locking assemblies and reinforced ribs to withstand higher belt tension.
How to choose a suitable conveyor pulley?
Selection should consider belt width, tension, power, working environment, lagging requirements and installation space. A professional turnkey solution is recommended for stable conveyor system operation.
