Pulleys are one of the most important component of the conveyor system. These are designed to perform tasks like providing tension to belt,power transmission and belt tracking. Conveyor systems performance and reliability depends on the pulley.
Pulleys are used for directional change in vertical plane in conveyor system & to form an endless loop for continuous operation. The necessary drive power is transmitted through pulleys. The pulleys are basically of two types Drive pulley and Non drive pulley.
Snub pulley is used to achieve higher angle of wrap on the drive pulley thereby increasing the traction. It also reduces the belt tension maximizing the life of the conveyor component.It is mounted close to the drive pulley on the return side of the belt.
Feature of motorized drive conveyor drum pulley for conveyor
1.Steady running, reliable quality and reduce maintenance;
2.Less movement longitudinally, rotating smoothly, extends the life span;
3.Various bearing housing and sealing structure are available for the customers choice;
4. Multipass labyrinthine sealing,preventing the mixed dirt and water immersed;
5.Manufacturing by steel pipe specially for of high precision roller, ensuring the strong load,
low shaking and less noise.

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 wing 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.
