Abstract
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.
