US Patent:

44496702, May 22, 1984

Filed:

Oct 29, 1981

Appl. No.:

6/316216

Inventors:

James J. Tloczynski - Parma OH
Clifford J. Ahola - Cleveland OH
Nicholas D. Rosenstein - Beachwood OH
James C. Rine - Lake City FL

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

B02C 712

US Classification:

241 35

Abstract:

A pellet feeder (A) feeds pellets of vulcanized rubber or other materials and water or another fluid at controlled rates into a mixing tank (30). An agitator (32) mixes the pellets and fluid into a slurry. The slurry is pumped from the mixing tank to a mill (C) by a pump (34). The mill has a receiving region (70) defined between a stator (48) and a rotor (68) for receiving the slurry. The stator and rotor define a peripheral grinding zone (72) around the slurry receiving region. An impeller (74) has vanes which extend from the upper surface of the rotor to an abrasive surface (82) of the stator such that the impeller vanes are ground at the same rate as the stator and rotor wear to maintain a fluid seal around the impeller blades. Fluid cylinders (50, 52) maintain a constant pressure between the stator and rotor. The stator has a plurality of recesses (86, 86') which preferably have downstream extending relief areas (214).
