Abstract
The invention relates to a centrifuge comprising a rotating drum (1) and comprising an ejection element (2) which rotates together with the drum in order to eject a cake (3) of solids, which is deposited on the inner side of the drum, in the axial direction (4). The ejection element (2) has a helix (5) which extends over the length of the drum. The helix (5) and the drum (1) are kinematically connected in such a manner that a reference point (A) at the circumference of the helix executes a rotational movement relative to the drum in the form of a sawtooth line (6, 8), with a first flank (7) of the sawteeth (8) corresponding approximately in its inclination (.alpha.) to the pitch (.beta.) of the helix whereas a second flank (9) of the sawteeth (8) corresponds to an approximately axial ejection movement.
