Patent ID: 7059552

Claim:
A comminution assembly for size reduction of particles in a slurry thereof to form a homogeneous product which comprises: a housing defined by co-planar circularly shaped chambers in tangential communication with a collision zone there between; an outlet conduit in fluid communication with said collision zone for drawing said homogeneous product from said housing; a wheel member positioned in each of said chambers, said wheel member comprised of an upper plate member having a circularly-shaped opening, a lower base plate member, and a plurality of radially extending arcuate vanes mounted to and disposed between said plate members; a hollow shaft member perpendicularly mounted to each of said upper plate members for introducing said slurry into said wheel member; and means for rotating said wheel members to accelerate said slurry towards said collision zone to effect particle to particle contact and therefore size reduction to form said homogeneous product.
