Eagle Crusher’s Ultramax crushing plants now have internally powered drum motors made by Van der Graaf to help protect components from demolition and recycling debris. Compared to an exposed drive system, the Van der Graaf motor and gear drive are enclosed within the outer shell of the conveyor drum motor. The motor rotates two-stage gearing that transmits power to the outer shell through a final gear ring that is fixed to the rotating shell. The space-saving configuration of the drum motors allows for a simple and economical conveyor drive system and a larger diameter head motor to drive the conveyor belting. The larger head motor allows the belting to make a more gradual 180-degree turn, which reduces the strain on belt fibers and extends belt life.
