ABSTRACT:
The invention relates to a pusher centrifuge (1) for the separation of a mixture (2) into a solid cake (3) and into a liquid phase (4). The pusher centrifuge (1) in accordance with the invention includes an outer screen drum (6) rotatable about an axis of rotation (5), a mixture distributor (7) arranged in the screen drum (6) with a pusher base apparatus (8) and an infeed device (9), with the pusher base apparatus (8) being arranged and designed such that the solid cake (3) is displaceable by means of the pusher base apparatus (8) and the mixture (2) can be introduced by the infeed device (9) via the mixture distributor (7) into an empty space (R) which arises on the displacement of the solid cake (3) by the pusher base apparatus (8). The mixture distributor (7) includes at least one funnel (10) for the pre-acceleration of the mixture (2), with the funnel (10) being rotatably arranged about a drive axis (11) and being rotatable at a pre-settable speed of rotation about the drive axis (11) by means of a drive (12).
