ABSTRACT:
A drum for a centrifuge has a shell with a radially outer layer of plastic resin free of fibrous material, a radially inner layer of a fine mesh metal fabric embedded in a plastic resin material, and a plurality of intermediate layers of fibers, such as glass fibers embedded in plastic resin material, with the fibers of adjacent layers extending in different directions. The ends of the drum are thickened, and secured to flanges of end plates by screws having axially extending holes. Radially extending holes at the center of the shell are provided with tubular inserts. The holes axially extending through the screws also extend substantially radially relative to the drum.
