Abstract
A centrifuge concentrator bowl has feed deposited onto a base of the bowl and includes a plurality of recesses at axially spaced positions along a peripheral wall of the bowl. The peripheral wall is formed of a rigid metal skeleton frame of rings and upstanding support members on which is molded a urethane liner material to form an integral structure with the rings located at ribs between the recesses. A fluidization water injection system includes an outer container on the bowl, which also acts as a clamping assembly and a plurality of liquid entry openings through the peripheral wall at the base of the recesses allowing flexing of the peripheral wall in response to changes in pressure in the fluidizing liquid. The bowl is formed of separate sections defined by a bottom concave base section and the cast skeleton wall all clamped together to allow replacement of the separate parts.
