Abstract:
An apparatus for dispersing solids in a liquid comprising:a) a containment;b) a variable displacement particle grinding means removably attached to said containment for selectively reducing particle size of said solids in said liquid comprising:i) a multi-shear rotary grinder, having a stationary, and a rotating, attrition plate having a linearly, adjustable rotor member, thereby defining a variable attrition zone, mesial said stationary and rotating attrition plates, and a plurality of descending grinding stages,ii) an impeller vane means, attached to said rotor member, for agitating said liquid in said containment and breaking said solids prior to said liquid entering said attrition zone;iii) intake means attached to said rotor member for importing said liquid and solids by suction into said attrition zone;iv) an intermediate member mesial said intake means and said attrition zone, said member having internal ports in communication with said intake vane means and said attrition zone, andv) a drive means connected to said rotary member for turning said rotating attrition plate.
