Apparatus for separating liquid and solid material has an auger having an auger screw and a tubular housing extending around the auger screw, the tubular housing having an opening in the top thereof to allow the solid material to be deposited through the opening into the auger screw. A screen extends around the auger and is spaced radially outwardly from the tubular housing to allow a mixture of the solid material and the liquid to be introduced between the tubular housing and the screen, whereby the liquid can flow outwardly through the screen while at least a portion of the solid materialis retained on the inner side of the screen. A motor is provided for rotating the screen about the auger to allow the thus-retained solid material to fall through the opening into the auger for removal by the auger, and a filter extends around the screen for filtering the liquid which drains through the screen, the filter and the screen being co-axially rotatable.
