ABSTRACT:
An improved vertical, centrifugal separator (100) includes a drive mechanism (142) to which is connected both a flight assembly (138) and a screen assembly (166). An inlet assembly (124) is positioned above the flight and screen assemblies for material (M) to be separated to be fed into the separator. This material is captured between the flight and screen assemblies and falls downwardly therebetween as separation occurs A pocket assembly (144) integral with the screen assembly is positioned between a discharge port of the inlet assembly and the upper end of the flight assembly. The pocket assembly creates a "basket" for catching material introduced into the separator through the inlet assembly, and replaces the upper portion of the screen assembly which previously was used to catch this material. The screen assembly includes a rotor (182) having a plurality of spokes (196) defining an outlet for separated solid material. The spokes have attached wear pads (210) to protect them from impacts with the solid material thereby to prolong the useful life of the rotor. An outlet assembly (216) for the solid material is positioned beneath the rotor. The outlet assembly has a side wall (218) lined with ceramic plates (242) to resist impacts from the solid material falling into the outlet assembly.
