Product Description
A conveyor will always consist of at least 2 pulleys, head pulley and tail pulley, with additional pulleys used depending on the configuration. Standard-duty pulleys are usually adequate for simple applications, but mine-duty and engineered pulleys are also available where heavy-duty pulleys are required.
Different kinds of conveyor pulleys
KONWEYOUR sells conveyor pulleys in all the following sub-categories:Â
Head pulleys
The head pulley is located at the discharge point of the conveyor. It usually drives the conveyor and often has a larger diameter than other pulleys. For better traction, the head pulley is usually lagged (with either rubber or ceramic lagging material).
Tail and CHINAMFG pulleys
The tail pulley is located at the loading end of the belt. It comes with either a flat face or a slatted profile (wing pulley), which cleans the belt by allowing material to fall between the support members.
Snub pulleys
A snub pulley improves the traction of the drive pulley, by increasing its belt wrap angle.
Drive pulleys
Drive pulleys, which can also be the head pulley, are driven by a motor and power transmission unit to propel the belt and material to the discharge.
Bend pulleys
A bend pulley is used for changing the direction of the belt.
Take-up pulley
A take-up pulley is used to provide the belt with the proper amount of tension. Its position is adjustable.
