What is a drum pulley?

Drum pulleys have been in use for centuries and continue to be utilized in many, many applications in our modern world. In heavy industry, their applications are on a much larger scale. Engineers design pulley systems with a great deal of consideration for the environment. For example, an industry with frequent dust and debris may require a self-cleaning pulley or special bearings and seals to protect it from the elements. Environments with wet and dry conditions will require specific pulley liners, and applications with extremely corrosive products will require stronger materials to support the operation.


In belt conveyor applications, the role of the pulley is threefold.

1) supporting the belt during changes in direction by the conveyor design.

2) transmitting drive forces to the belt, and

3) guiding or training the belt.


The drive pulley transmits the driving force to the belt and can be located at the head or discharge end of the conveyor, in the return chain, or at the tailor loading end of the conveyor.


The cushion pulley is located near the drive pulley to provide more contact arcs between the belt and pulley for maximum traction when driving the belt.


The head pulley is located at the discharge end of the conveyor and in simple conveyors is usually the drive pulley.


The tail pulley is located at the loading end of the idler conveyor and in simple conveyors is usually the winding pulley.
