ABSTRACT:
The apparatus for separating a solid-liquid mixture has a housing with a metal screw conveyor adapted to rotate relative to the housing on a common longitudinal axis. The conveyor has helically-formed flights about its axis. Replaceable inserts are mounted on the entire circumference of the flanks of the flights with each insert having metal secured to the flights and integral wear-resistant material adapted to function as the working surface.
The inserts are formed by first making a metal annular member of the same material as the conveyor flight. The wear-resistant, hard-facing material is then deposited on one radial surface of the metal annular member in a manner to simultaneously form and fuse the wear-resistant, hard-facing material to the annular member. The metal part of the annular member is then machined to proper dimensions and the annular member cut into segmental inserts. The segmental inserts are then mounted on the conveyor flights.
