A centrifuge concentrator bowl includes a plurality of fluidized recesses at axially spaced positions along the peripheral wall. Each recess is defined by two side walls which has water injection holes for fluidizing materials collecting in the recess. Some of the recesses are at least partly defined by a removable insert member arranged to be attached to a suitable mounting on the wall of the bowl. Each insert member includes a face portion defining a surface facing toward the axis of the bowl for engaging the slurry and preventing wear. The face portion may include a side portion on one side or both sides located radially inwardly of a rib on a respective side of the recess and at least partly covering the rib so as to prevent the slurry from contacting the rib and causing wear to the rib.

Centrifugal separator with a separate strip insert mounted in the bowl

A centrifuge concentrator bowl includes a plurality of fluidized recesses at axially spaced positions along the peripheral wall. Each recess is defined by two side walls converging toward a base which has water injection holes for fluidizing materials collecting in the recess. The volume within which collection occurs is defined by a replaceable plastic strip member across the recess spaced from the base so that a water channel is formed inside the bowl between the base of the recess and the strip. Water from the channel is injected through holes in the strip in a generally tangential direction around the recess. The use of the replaceable strip allows the injection openings of the bowl to be tailored to requirements and/or to be cleaned of scale by rapidly removing and replacing the strips in the bowl.
