1. Drive Pulleys
Function: Drive pulleys are integral to the conveyor system, providing the necessary force to move the belt and its load. They are driven by a motor and are responsible for transmitting power to the belt.
Features: These pulleys are usually equipped with a crown face to ensure proper alignment and reduce slippage. They are designed to handle high torque and maintain efficient operation under heavy loads.
2. Idler Pulleys
Function: Idler pulleys support the conveyor belt and help maintain its alignment and tension. They do not drive the belt but play a crucial role in guiding it and ensuring smooth movement.
Features: Idler pulleys come in various types, including plain, return, and impact idlers. They are designed to handle different load conditions and belt speeds, ensuring the longevity and smooth operation of the conveyor system.
3. Tail Pulleys
Function: Tail pulleys, also known as end pulleys, are located at the end of the conveyor system. They are crucial for guiding the belt back to the drive pulley and maintaining belt tension.
Features: Tail pulleys are typically non-drive pulleys and are designed to withstand the return load of the belt. They help in reducing wear and tear on the belt by providing smooth and controlled movement.
4. Snub Pulleys
Function: Snub pulleys are used to increase the belt wrap angle around the drive pulley, enhancing the grip and improving the efficiency of the conveyor system. They are particularly useful in situations where additional traction is required.
Features: These pulleys are strategically positioned to optimise belt performance and prevent slippage. They are designed to handle various load conditions and maintain consistent belt tension.
5. Take-Up Pulleys
Function: Take-up pulleys are used to adjust the tension of the conveyor belt. They are essential for compensating for belt stretch and ensuring optimal tension throughout the conveyor system.
Features: Take-up pulleys come in various designs, including manual and automatic versions. They help in maintaining proper belt tension and alignment, which is crucial for smooth operation and preventing excessive wear on the belt and components.
