ABSTRACT:
Comminuting and classifying apparatus of the re-entrant circulating stream jet type includes a vortex chamber and jet means. The feed means includes a central conical recess in one wall of the chamber, a coaxial circular chamber opening into said recess and means to direct the material and gaseous carrier fluid into said chamber tangential to the wall of the chamber so that the material and carrier fluid is added to the vortex with a rotative velocity. The apparatus may also be provided with means for jet and anvil comminution of feed material and/or recirculating material. The chamber may include an annular shoulder for skimming undesirable particles in the feed material.
