ABSTRACT:
To provide a reliable solid-liquid separating method and apparatus for a slurry, even though the solid component of the slurry is finely divided particles and/or of a shape difficult to entangle, without exudation through gaps in processed portions and, also, with no need to exercise a maintenance work such as replacement of filters, a solid-liquid separating apparatus includes a mold having a cylindrical inner peripheral surface, a gate for opening and closing a second open end of the mold, and a pressing rod slidable into the mold to compress the slurry. Sheet-like fibrous filters are placed on a leading end face of the pressing rod and an inner surface of the gate to seal gaps between the mold and the pressing rod and between the gate and mold. With the filters so placed, the slurry within the mold unit is compressed to provide a solidified product, thereby accomplishing solid-liquid separation.
