Wear resistant centrifuge tile assemblies are disclosed that include a backing portion and a wear-resistant tile. Wear resistant centrifuge tile assemblies are provided with self-fixturing features to provide a desired mounting position and to restrict movement of the wear-resistant tile with respect to the backing plate during bonding. The self-fixturing features provide the ability to perform repeatable and consistent bonding of the wear-resistant tile to the backing plate.

A centrifuge basket includes a frustum-shaped hollow body defining a pair of opposed ends, being a larger end and a smaller end. The body defines an internal screening surface extending between the ends, the screening surface defining a plurality of apertures arranged to drain liquid from within the body. A plurality of ribs project into an interior of the body from the screening surface, the ribs being arranged in a plurality of annular arrays. The arrays are spaced axially along the screening surface and the ribs of at least one of the arrays are arranged transversely, at a defined included angle, relative to a generatrix line that forms a shape of the screening surface.

A centrifuge provided with: a bowl having a plurality of extension lugs formed on an opening rim section at one end of the bowl in the axial direction, the extension lugs being spaced apart from one another in the circumferential direction; a screw conveyer rotatably housed inside the bowl and rotatable at a different rotational speed than the bowl; a hub forming solid discharge ports between circumferentially adjacent pairs of the extension lugs, the hub connecting to the extension lugs and covering an opening of the opening rim section from the axial direction; and a wear-resistant sleeve including a sleeve body and a flange. The sleeve body covers lug inner surfaces of the extension lugs and the flange extends in an arced shape along the opening rim section. The sleeve body is attached with axially extending bolts to the opening rim section at a position that avoids the extension lugs.

A centrifugal separator includes a bowl with a conical part with a narrow discharge end comprising a radial surface; an end member opposite the radial surface; a number of distance members extending between the radial surface and the end member and providing outlet openings for a separated solid or heavy phase between adjacent distance members; and wear resistance members covering surfaces at the outlet opening. The wear resistance members include plate members and bushing members. The bushing members include mantle portions surrounding respective distance members. The plate members each cover a portion of the radial surface between adjacent bushing members.

A scroll conveyor tile protection or any other material subject to wear with a weldable support and a wear resistant insert, not necessary weldable. The support is fit with a flat surface and shoulder allowing for precise positioning of tile on a scroll flight to be protected. At least one opening, preferably at its center, allows for insertion and assembly of a complementary shaped insert. The unit setting up on the scroll flight and the contact between the flight faces and the unit faces allows for creating a dove tail locking system. Welding of the support permanently insures locking of the system and insert being maintained without being otherwise fixed beyond this mechanical clamping.
