ABSTRACT:
A centrifuge bowl includes a flat base and a generally conical peripheral wall upstanding from the base. A jacket surrounding the bowl allows injection of water from a chamber between the bowl and the jacket through openings in the peripheral wall into the bowl for fluidization of materials within the bowl. A feed duct extends to the base and discharges feed materials onto the base for moving outwardly onto the peripheral wall and passing over the peripheral wall. A first portion of the peripheral wall is smooth, imperforate and frusto-conical. At the upper edge of the first portion is provided a pair of axially spaced recesses with injection openings at the base of the recesses for the fluidizing water. Heavier materials collect within the recesses and are discharged outwardly through a plurality of controlled discharged openings around the recesses. Lighter materials escape through the open mouth of the bowl.
