Motorized Drum Motors (Food, Packaging, Aggregate, Mining)

DESIGN BENEFITS

Increase Operator  Safety

All external moving parts such as gearbox, chains, motor, chain guard and pillow block bearings that present safety hazards are eliminated .

Lower Energy and Operating  Costs

Van der Graaf drum motors operate at 96% mechanical efficiency resulting in lower operating cost compared to conventional drives .  The higher efficiency of the internal drive can result in energy savings of up to 30% over conventional exposed-drive conveyors .

Reduce Noise Levels

Our gears are manufactured using high quality alloy steel, machined and honed to AGMA/DIN 6 standards, reducing noise to minimal decibel levels which exceeds OSHA requirements for noise .

Reduce Maintenance  and Downtime

Having no external moving components eliminates the need for continual chain adjustment and yearly maintenance . Our motors are virtually maintenance free, requiring only an oil change after 50,000 hours of operation, which can be performed without removing the drum motor from the conveyor .

Enhance Space Utilization

Low profile of the drum motor results in a streamline appearance and allows to fit more belt conveyor into less floor or overhead space .   Allows higher density and multiple applications .

High Pressure  Wash down

Extreme pressure wash down with sanitizer is easily performed without the need to shield sensitive components since the completely sealed drum motor has no external components to protect . Motors The drum motor houses all components internally, eliminating the need for external components like motor, gearbox, chain, chain guard and pillow block bearings. The drum motor rotates a gear module which transmits power to the outer rotating drum. Drum motor installation is quick and easy, requiring less time to install than exposed conveyor drives.
