WEAR-RESISTANT HOUSING FOR AN EXTRUSION DEVICE

摘要

A corrosion-resistant and wear resistant housing for a screw extruder having one or more axis-parallel bores, each of which accommodates a screw of the extruder. Support sleeves, which have a smaller internal diameter than the screw bore or bores and which guide the rotating screw or screws are disposed in the two end regions of the housing poritons, whereby the corrosion and wear caused by the material being extruded are primarily restricted to the support sleeves.
