ABSTRACT:
A pump adapted to ingest, reduce and deliver combined fluid and solid materials. The pump includes a centrifugal pumping means with a volute chamber, central inlet opening, a substantially tangential outlet opening and a vaned rotor within the chamber; a milling means at and about said inlet opening and including an elongate milling ring with upstream and downstream ends and elongate circumferentially spaced grooves and teeth about its inner peripheral portion and a milling disc rotatable within the ring and drivingly coupled with said rotor, said disc carrying circumferentially spaced shearing blades overlying the downstream end of the ring and shearing blocks with circumferentially and radially disposed material engaging surfaces within the confines of the ring; and material feed means to reduce and deliver material to the milling means and including a material conducting bore upstream of the milling ring, a lateral material supply duct communicating with the bore and an elongate helical screw in the bore and drivingly coupled with the disc and a prime mover drivingly coupled with one end of that rotary assembly made up of said rotor, disc and screw.
