Abstract
A comminutor and a pump are assembled together so that they are driven by the same prime mover, such as a tractor power take-off, the pump being arranged to draw liquid, such as sewage, into a comminution chamber containing a rotating hollow cylinder which functions as a combination cutter and strainer. The solids in the sewage are comminuted until they are of a size small enough to pass through openings in the cylinder into the interior thereof from which the comminuted particles are pumped to a desired location, such as an irrigated field by the pump. The pump shaft has a drive shaft extension that extends through the center of the rotating cylinder to drive a planetary gear system arranged so that the rotating cylinder is driven at a speed much less than the pump speed.
