ABSTRACT:
These and other objects of the present invention are achieved by a comminution apparatus comprised of a housing member formed with co-planar circularly-shaped chambers in chordal juxtaposition to each other thereby forming a collision zone therebetween and wherein wheel members having radially disposed directional vanes are positioned for rotation in each cylindrically-shaped chamber and wherein an inlet fluid conduit or a slurry of particulate matter to be treated is in axial fluid communication with each wheel member and wherein each wheel member is caused to be rotated in a direction to accelerate the slurry towards the collision zone and to affect particle size reduction by particle collision and wherein an outlet conduit is in fluid communication with the collision zone for withdrawing a slurry of size reduced particles from the comminution apparatus.
