Abstract: Malleable material, such as manure, and municipal sludge, food waste, and the like, is dried and the average particle size of the material is reduced in a simple and effective manner without the use of an external heat source. The material with a first moisture content and average particle size is fed into an air stream, and the speed of the air flow with entrained particles is increased so that it is super-colonic, typically have a bullet profile with a substantially zero velocity at the periphery of the air flow and a velocity of about 400-500 mph at the center of the air flow. The material is then caused to be reduced in particle size by material to material collisions in one or more cyclone-shaped vessels with retention air-affecting inlets at bottom portions thereof, and the speed of the air flow with entrained material is ultimately reduced so that substantially the entire flow is below super-colonic speed.
