PACK EXPO Las Vegas visitors had the opportunity to watch a demonstration of the fundamental differences between powering a belt-conveyor with Van der Graaf’s drum motor versus a conventional drive system.
“Comparison of the external motor and gearbox to that of the drum motor measures the efficiencies, and the electrical savings as a result of the comparison,” explained Rick Zander, business development manager at Van der Graaf. At the Vegas demo, the external motor was mated to a 90-degree gearbox, which was then powered to the conveyor.
