ABSTRACT:
A sedimentation centrifuge includes a bowl which is supplied with a feed mixture, i.e., a solid-liquid mixture, from a supply pipe. When the bowl rotates at high speed, heavy solids are displaced radially outwardly toward and sedimented on the inner wall surface of the bowl. The solid particles are then discharged through a discharge hole of the bowl and an outlet passage by a screw conveyor in the bowl. During rotation of the bowl, fins on the screw conveyor assist in separating the liquid into heavy and light liquid phases with increased separation efficiency. The separated heavy and light liquids are separately discharged from the bowl through respective outlet passages.
