ABSTRACT:
In a continuous-feed filtering- or screening-type centrifuge, first dewatering a particulate material, then reslurrying the particulate material, and subsequently again dewatering the particulate material in a sequence along a cake flow path extending through the continuous-feed filtering- or screening-type centrifuge. The first dewatering, the reslurrying and the subsequent dewatering are performed in respective compartments disposed along the cake flow path. The compartments are defined in part by a plurality of gates, baffles, or weirs extending outwardly from a hub of the centrifuge. Outer ends of the gates are spaced from a bowl wall to define respective cake flow gaps which limit the thickness of a cake layer moving along the cake flow path.
