Mining and aggregate processing equipment operates continuously under harsh conditions creating constant maintenance concerns. Abrasive environments that include dirt, dust, grit and humidity place extraordinary demands on conveyor belts and drive units. Heavy loads and impact shock intensify these assaults on the entire conveyor system. Specifically engineered Van der Graaf Drum Motors are built to endure these extreme conditions and handle the demands of virtually every application.
The Van der Graaf Drum Motor or motorized pulley houses all components internally, eliminating the need for external components like motor, gearbox, chain, chain guard and pillow block bearings. This reduces operating and maintenance costs, improves safety conditions and because it is completely sealed our drum motors can operate in extreme environmental conditions.
The low profile motor features heavy-duty bolt-on cast iron end caps, combined with heavy duty mining grade cassette seals that resist corrosion and contamination. Heavy duty subcomponents ensure long life and reliable operation.
