The Drive
Specially designed drive systems for optimal separation results
The solution to a separation problem depends on the drive of the centrifuge. The centrifugal force required for solid-liquid separation is determined by the speed of the bowl or screen. To achieve the right speed for optimum separation results, it is often necessary to keep the speeds variable. Our specialists will customize the required drive control for your application.
In screen scroll centrifuges and decanters, the differential speed of the solids conveying screw to the bowl is also critical. It determines the residence time of the solids in the centrifuge and therefore the separation efficiency.
The correct differential speed for your separation task is determined by selecting the right gear. The differential speed can be constant or variable. In the latter case, the backdrive is used, where the otherwise fixed input shaft of the gear is also driven. If you want to keep the screw speed completely independent of the bowl speed, hydraulic drives (Viscotherm) or two-stage gearboxes with an upstream differential planetary stage are used.
The drive system is continuously monitored to ensure the operational safety of your centrifuge. Overspeed, overcurrent and slippage are detected and reported to the machine control system for action.
