Abstract

A solid sleeve worm centrifuge having a cylindrical separating portion and a conical discharge portion is provided with a static plate attached to the rotating worm in the area of transition from the cylindrical portion to the conical portion. The static plate prevents the backflow of solids already precipitated from the conical portion to the cylindrical portion of the centrifuge. Intensive dehydration of the separated solids is thus achieved, so that the solids may be stored directly or processed further without additional liquid removal treatment. A liquid withdrawal conduit is provided in the cylindrical portion of the centrifuge to continuously remove liquid separated from a solid-liquid mixture.
