Abstract
In a pusher centrifuge comprising substantially cylindrical sieve or straining drums which simultaneously rotate but also oscillate relative to one another, and a pusher bottom or base, the pusher edge of at least one sieve or straining drum is provided with inclined surfaces which impart in the transverse or circumferential direction a motive component to the centrifuging or solid material transported in the axial direction. By virtue of the thus generated shearing effect, the compacted solid material cake is torn open or disintegrated during the forward feed and the dewatering performance is improved.
