Abstract

A pulverizer device for liquid handling systems which chops solid and semi-solid materials in the liquid to prevent plugging of and damage to pumps and other equipment in the system. The pulverizer device includes a housing having an inlet opening and a discharge opening and a screen disposed in the housing. A blade operates on the inlet side of the screen to chop material which initially will not pass through the screen. It is preferred that the blade be operated by a hydraulic motor, and that the housing have a sump with a clean-out on the side of the housing near the blade and screen for removing unpulverizable materials from the housing.
