Abstract

A continuously operating screw ejection centrifugal separator. The drum and the screw are driven by an epicyclic gear train. Changes in torque between the screw and the drum of the centrifuge are measured and the differential speed of the screw and drum is controlled so as to obtain substantially steady state operation of the separator. For the control, a second epicyclic gear train is associated with the first-mentioned epicyclic gear train.
