Abstract

A comminutor and pump are assembled together with 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. Various drive arrangements are provided to drive the pump at a relatively high speed and the rotating cylinder at a relatively low speed.
