  • Patent number: 6123018
    Abstract: A method and apparatus for extracting liquid from a liquid-containing slurry. In the preferred embodiment, the apparatus (10) includes a plurality of interconnected press assemblies (12), the outlet (82) of one press assembly (12) being connected to the inlet (92) of a successive press assembly (12). Each press assembly has a foraminous cylindrical container (14), and a two-part piston assembly (18) movable between extended and retracted positions within the foraminous container (14). During operation, a pump (90) continuously feeds slurry under pressure through the inlet of the first press assembly to cause liquid within the first stage slurry upstream of the two-part piston assembly (18) to be radially expressed through the foraminous container (14). After a suitable amount of liquid has been extracted from the first stage slurry, batch processing of the partially dewatered slurry will commence.
