Patent ID: 8808155

Claim:
A centrifuge bowl for use in an apparatus for separating intermixed particulate materials of different specific gravity in a slurry where the apparatus includes a feed duct for feeding the slurry into the bowl during rotation of the bowl so that during rotation of the bowl the intermixed particulate materials flow over a peripheral wall of the bowl for collection of heavier particulate materials on the peripheral wall and for discharge of the lighter particulate materials in the slurry from the open mouth, the bowl comprising: a peripheral wall surrounding an axis with the wall generally upstanding from a lower end to an open mouth; wherein the peripheral wall includes a supporting frame formed of a rigid material and a flexible liner material molded onto the supporting frame; the supporting frame being defined by a plurality of ring members which are axially spaced each from the next to define a space between each ring member and the next; the supporting frame including a plurality of generally axially extending support members; wherein the axially spaced ring members are connected each to the next by the generally axially extending support members which are angularly spaced to define a space between each support member and the next; the flexible liner material being molded onto the supporting frame to define an inner surface of the peripheral wall and to fill the spaces between the ring members and between the support members.
