Abstract: In a centrifugal apparatus for separating wetting material carried on particulate matter or chips, such apparatus includes a truncated conical shaped bowl into which the particulate matter or chips are deposited for centrifugal separation. A number of equidistantly spaced and radially aligned vanes are secured to the inner surface of the bowl adjacent the truncated end to collect incoming particulate matter or chips, and to establish a buffer layer, reducing the abrasion on the bowl caused by the insertion of further particulate matter or chips.

Abstract: In a horizontal centrifugal apparatus for separating wetting material carried on chips, such apparatus includes a conically shaped bowl carrying vanes distributed about its inner face with the midpoint of the length of said vane lying on a radius from the horizontal axis of bowl rotation such that the vane leading ends and trailing ends are about fifteen degrees of the radius at the midpoint of such vanes to impose an impediment to the rate of erosion on the vanes.

Abstract: A horizontal screen separator of the present invention includes a base having a housing mounted thereon which contains an horizontal screen basket for receiving product to be dried. The basket is rotatably and vibrationally driven to dry the product. The separator includes two motors, one to impart rotational motion to the basket and the other to impart vibrational motion to the basket. The basket is rotatably fixed to a shaft driven by the rotating motor. The vibratory motor drives a shaft, operative contact with the rotating shaft, having an eccentric mounted thereon. The vibratory motor drives the vibratoy shaft to induce vibration in the basket. The basket also includes a lip or extension formed from screen as a right cylinder to increase the drying time of the product.

Abstract: A cone frustum is provided for a centrifugal separator to shield the area of the separator's screen at the top of the flight assembly from the initial impact of the material which is introduced into the separator. The cone frustum is spaced above the flight assembly and below the inlet to shield the portion of the screen that is at the top of the flight assembly. The cone frustum is spaced radially inwardly from the screen and outwardly from the outlet. The cone frustum shields the part of the screen which wears most quickly to extend the life of the separator's screen assembly. The cone frustum is partially perforated to allow for initial dewatering of the material introduced into the separator. The slope of the cone frustum is equal to or less than the slope of the screen of the separator.

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.
