ABSTRACT:
A centrifuge concentrator bowl of the type having a plurality of fluidized recesses at axially spaced positions along the peripheral wall of the bowl is modified by providing an increase in width of the area between each fluidized recess and the next. In the area between the fluidized recesses is provided a shallower recess which is non-fluidized which provides some collection of materials. The bowl is of a frusto-conical shape so that the open mouth is larger than the base and a restricting ring is attached at the open mouth to define and inner edge of a diameter less than that of the uppermost recess and approximating that of a recess lower in the bowl. The uppermost recess is a fluidized recess and at least one of the lowermost recesses are non-fluidized.
