ABSTRACT:
A scroll and screen centrifuge especially suited for processing abrasive materials in which the surfaces of the screw flights on the scroll members contain recessed abrasion resistant shields. The abrasion resistant shields have an upper exposed surface flush with the front surfaces of the screw flights. The scroll members also have feed openings designed for material flow which further reduces the abrasion of the scroll member.
