1. A set of recess insert members: for use in a centrifuge bowl for use in an apparatus for separating intermixed particulate materials of different specific gravity in a slurry where the apparatus includes: each of the recess insert members comprising an elongate body shaped to extend only over a part of the height of the peripheral wall such that the set of recess insert members can be arranged at axially spaced positions in the bowl; each of the recess insert members being shaped to extend around at least a part of the annular periphery of the peripheral wall; each of the recess insert members being formed from a resilient material: each of the recess insert members having at least one abutment element thereon for engaging a respective one of a plurality of co-operating elements of the bowl for holding the recess insert member in the bowl during rotation of the bowl; the abutment element and the cooperating element being arranged such that the recess insert member is readily removable and replaceable; each of the recess insert members being shaped to define an upper side wall of one of the recesses and a lower wall of a next adjacent one of the recesses with a rib therebetween such that, when two of the recess insert members are mounted in said axially spaced positions side by side, the recess insert members cooperate to define said one of the recesses therebetween.
