The production process of the drive pulley involves several key steps:

  1. Mold creation
  2. Casting of the pulley
  3. Selection of raw materials
  4. Production of the drive pulley
  5. Testing for quality assurance
  6. Antirust treatment for longevity
  7. Separate inspection to ensure performance
  8. Marking for identification

What is the difference between a drive pulley and a head pulley?

  • Drive pulley is used to transmit power, while head pulley is used to change the direction of the belt.
  • Drive pulley is connected to the motor, while head pulley is located at the end of the conveyor system.
  • Drive pulley is usually larger in size compared to the head pulley.
  • Drive pulley is responsible for tensioning the belt, while head pulley guides the belt along the conveyor.
  • Drive pulley is essential for power transmission, while head pulley is crucial for belt tracking.
  • Drive pulley is dynamic, while head pulley is static.
  • Drive pulley is directly powered, while head pulley is driven by the belt.
