Patent ID: 7229037

Claim:
A comminution assembly for size reduction of particles in a slurry thereof to form a homogeneous product which comprises: a housing formed with circularly-shaped chambers in tangential communication defining a contact zone; an outlet conduit in fluid communication with said contact zone for drawing said homogeneous product from said housing; a disk member positioned in each of said chambers, said disk member comprised of an upper plate member having a circularly-shaped opening, a lower base plate member, and a plurality of radially extending vanes mounted to and disposed between said plate members; a hollow shaft member perpendicularly mounted to each of said upper plate members of each of said disk members; an inlet shaft member positioned in each of said hollow shaft members, said inlet shaft members having an elbow horizontally disposed between said upper plate member and said lower plate member, said shaft member and said elbow rotatable with respect to said hollow shaft members and said disk members to guide said particulate matter in said slurry to said vanes for introducing said slurry into said disk member; and means for rotating said hollow shaft members and disk members to accelerate said slurry towards said contact zone to effect particle to particle contact and therefore size reduction to form said homogeneous product.
