ABSTRACT:
A press for continuous expressing of a liquid from a particulate liquid/solid mass of the type including a conveyor screw or auger advancing the mass through a tubular housing which is provided with drainage perforations. The compression and advancement of the material through the perforate section is effected by the face of a reciprocating annular sleeve, the stroke of the sleeve being so arranged that at least one-half of the travel of said face takes place within the perforated area. The frequency of the reciprocating movement of the sleeve is three cycles per second or more, to reduce resistance to the passage of the mass through the housing. The device is capable of a considerable increase in dewatering performance, as compared with known devices of the type operating more or less solely with a conveyor screw.
