Abstract
The present conveyor system includes an external bowl with an internal screw conveyor of one or more flites which is rotated to cooperate with the bowl. The bowl and conveyor provides scrolling actions so that a mixed fluid introduced therein is segregated to separate the heavier parts from other parts in the fluid. One aspect of the disclosure is the incorporation of a single motor connected either to the bowl or conveyor, and a output power transmission connected between said bowl and conveyor. The transmission assures that the bowl and conveyor rotated in the right direction to provide the scrolling action which is maintained at as desired ratio with respect to bowl speed. In the preferred form, this includes a dual input, dual output transmission, and a connection so that only one motor source is needed.
