Conveyor Drum Pulleys: Head, Tail, Snub and Take-up Pulley

Conveyor drum pulleys offer several advantages in belt conveyor systems, contributing to their efficient and reliable operation. Depending on their specifications, conveyor pulleys can serve in a variety of roles or positions.

Components of a Drum Pulley

1. Steel Shell (the thickness is available in 12mm, 14mm, and more.)
2. End Disc
3. Hub
4. Conveyor Pulley Shaft
5. Locking Assemblies (optional)
6. Plummer Block (optional)
7. Drum Pulley Rubber Lagging

Conveyor Pulley Lagging Types

Pulley laggings use on a variety of pulleys that provides a cost-effective and most effective solution to correct a belt slippage, increase friction and prevent material build-up, along with additional long term system benefits.

1. Smooth Rubber Lagging,
2. Diamond Rubber Lagging,
3. Ceramic Lagging,
4. Chevron Rubber Lagging,
5. Herringbone Rubber Lagging.

Roles of Conveyor Drum Pulleys

• Head Pulley

  A head pulley, also known as a head drum or drive pulley, is a key component of a belt conveyor system. It is located at the discharge end of the conveyor and is connected to the motor, often through a gearbox. The primary function of the head pulley is to drive the conveyor belt and move materials along the conveyor.

• Drive Pulley

  The conveyor drive pulley, a drum pulley, is a key component of a conveyor system, serving the purpose of providing the driving force to move the conveyor belt. It is typically connected to a motor or other power source to generate motion.

• Tail Pulley

  A conveyor tail pulley, also known as a terminal or bend pulley, is a key component in belt conveyor systems. It is located at the end of the conveyor line and is often mounted on a tensioning device to provide a point of redirection for the returning conveyor belt.

• Snub Pulley

  A snub pulley is a type of conveyor pulley that is typically located at the end of the conveyor near the drive pulley. Its primary function is to increase the wrap angle of the conveyor belt around the drive pulley, thereby increasing the traction between the belt and the pulley.

• Take-up Pulley

  A take-up pulley is a critical component in a belt conveyor system, specifically designed to maintain proper tension in the conveyor belt. It is part of the take-up device, which compensates for variations in belt length caused by changes in load, thermal expansion, and other factors.

• Bend Pulley

  A bend pulley is a type of conveyor pulley used to redirect the conveyor belt as it passes around a bend or curve in the conveyor system. Bend pulleys are strategically placed at locations where the conveyor belt changes direction to maintain proper belt alignment and reduce the likelihood of belt tracking issues.
