A pulverizer/grinder configured, its principle embodiment, to process drilling mud having cuttings utilizing a shaft on a horizontal axis having multiple rotors emanating therefrom. The rotors are surrounded by a cylindrical housing having inner walls situated near the tips of the rotors, each rotor further including first and second pulverizing members. The upper portion of housing includes input ports for the ingress of cuttings, drilling mud, and fluid, the lower portion of the housing including a cuttings screen having the desired aperture size for the egress of appropriately ground cuttings, particles, and fluid. Included with the system is a specially designed lug which emanates from the inner surface of the upper housing unit, the lug configured to securely communicate with the upper edge of the cuttings screen, securely holding same in place and preventing the buildup of debris thereabouts. The shaft utilizes a unique seal cartridge for lubrication between the pulverizer/grinder housing and pillow block bearings. A unique rotor blade configuration optimizes grinding efficiency, providing a carbide, angled rectilinear design. The pulverizer/grinder of the present system is designed to be directly fed from a hopper in conjunction with a shell shaker, with the pulverizer/grinder mounted upon a slurry tank for receiving the processed cuttings and fluid. Alternately, the pulverizer/grinder of the present system may be utilized, wet or dry, to pulverize aggregate and other materials in other, non-oil field contexts.
