ABSTRACT:
A centrifuge bowl for separating heavier particles from lighter particles and water comprises a first conical bowl wall leading to a pair of annular recesses at actually spaced positions. Each recess is generally re-shaped with an upper side wall, a lower side wall and a base. The base contains a plurality of angularly spaced discharge ducts each having a mouth projecting through the base into the interior of the bowl for collecting the heavier particles. A pinch valve is formed as an integral assembly with the mouth and duct and is mounted within a housing carried within the wall of the bowl. The housing, valve and duct can therefore be removed as a separate assembly by pulling from a chamber within the wall of the bowl. A compression fluid supply duct passes through the wall to communicate with the chamber. Each recess includes injection openings in the upper and lower side walls of the recess arranged to inject fluidizing water in a direction generally parallel to the base and across the mouth of each discharge duct. The injection openings are inclined so as to tend to direct the water around the recess.
