Abstract: In a centrifugal separator having a vertical drive mechanism including a drive shaft, a flight assembly attached to the drive shaft, a frustoconical screen assembly around the flight assembly driven by the drive mechanism and a rounded support basket to seat the screen, a method of assembling the screen within the basket. The method includes inserting the screen in the basket, pulling the screen upward to achieve a rounded condition, attaching the lower part of the screen to the lower part of the basket, and attaching the upper part of the screen to the upper part of the basket by tightening bolts.

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.

Abstract: In a horizontal centrifugal separator there is included a housing that rests by means of cushioned supports upon the ground, foundation, or the like, with the housing providing for the bearing mounting of a shaft that connects with a revolvable bowl, with both of said shaft and bowl being arranged substantially along a horizontal axis; the bowl includes a series of vanes extending from its interior surface, arranged between its base and the rim portion, with the rim portion having a series of perforations therethrough so as to allow for separation of the coolant from the metal chips as accumulated in the metal working industry. A chute also mounts upon the housing and has its discharge end extending into the bowl, and further includes a deflector that is arranged approximate its end, and therein allows for the continuous delivery of chips to the bowl and their uniform distribution along its interior surface to facilitate the centrifugal separation of any coolant from the chips.
