Abstract
A wet grinding machine which includes a grinder head, an annular stator having a mounting portion mounted on the grinder head and joined by a body portion to a skirt portion, and a rotor rotatably mounted on the grinder head. The rotor includes a hub portion joined by an annular body portion to an annular skirt portion inside of the annular stator. Outwardly extending slots in the body portion of the rotor define shearing blades in the body portion. Outwardly extending shearing slots in the body portion of the stator are opposed to the shearing blades. Each of the shearing slots slopes and overlaps at least one adjacent shearing blade. As the rotor turns, each of the blades is constantly opposed to and addresses at least one of the shearing slots. There are inlet openings in the stator skirt and in the rotor skirt. The rotor is turned to cause the rotor blades to induce a slurry to flow through the inlet openings of the stator skirt and rotor skirt and rotor body to the shearing slots and to shear particles of slurry entering the shearing slots. The stator skirt being extendable to receive slurry to be ground at a desired location spaced from the grinder head, and an eductor for adding material to the slurry moving through the rotor skirt so the material is substantially evenly mixed in the slurry exiting from the grinder head.
