Abstract
The invention relates to a double pusher centrifuge including a screen drum (3) rotatable about an axis of rotation (2) for separating a mixture (4) into a solid material cake (5) and a liquid phase (6), a mixture distributor (7) arranged in the screen drum (3) and having a pusher base device (8), which is arranged to be movable to and fro along the axis of rotation (2), so that the solid material cake (5) is alternately displaceable with an outer ring zone (9). Furthermore, the double pusher centrifuge includes an infeed device (10) with which the mixture (4) can be introduced via the mixture distributor (7) into an empty space (11), which arises adjacent to the outer ring zone (9) on displacement of the solid material cake (5) by the pusher base device (8). In this arrangement the pusher base device (8) has acceleration surfaces (12) on both sides, which are inclined at a pre-determinable angle of inclination (γ) with reference to the radial direction, so that the mixture (4) introduced by the infeed device (10) can be accelerated to a pre-determinable peripheral speed before reaching the screen drum (3).
