Abstract:
Centrifuge comprising a rotating drum and an ejection element which rotates together with the drum in order to eject a cake of solids, which is deposited on an inner side of the drum, in an axial direction of the drum, the ejection element having an ejector surface in the form of a screw-shaped helix, the helix and the drum being kinematically connected so that a reference point at a circumference of the helix executes a rotational movement relative to the drum in the shape of a sawtooth line, a first flank of the sawtooth line corresponding approximately in its inclination (&agr;) to a pitch (&bgr;) of the helix and a second flank of the sawtooth line corresponding to an approximately axial ejection movement.
