Abstract
The invention relates to a centrifuge comprising a rotating drum ( ) and comprising an ejection element ( ) which rotates together with the drum in order to eject a cake ( ) of solids, which is deposited on the inner side of the drum, in the axial direction ( ). The ejection element ( ) has a helix ( ) which extends over the length of the drum. The helix ( ) and the drum ( ) 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 ( ), with a first flank ( ) of the sawteeth ( ) corresponding approximately in its inclination (&agr;) to the pitch (&bgr;) of the helix whereas a second flank ( ) of the sawteeth ( ) corresponds to an approximately axial ejection movement.
