A method for separating materials, in which a mixture of materials is guided through a channel in a direction of flow that extends at least approximately parallel to the gravitational field. Utilizing a wash fluid conveyed through the channel in a direction transverse to the direction of flow of the mixture of materials, at least one material component of the mixture of materials that is to be separated is displaced from the mixture of materials and removed from the channel. A device is also provided that is particularly suitable for carrying out the method.

Method and device for separating materials

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.
