MULTI-STAGE SIZE REDUCTION, BLENDING AND DRYING SYSTEM AND METHOD

摘要

A system and method for comminution, blending and processing of particles of a material and an additive using a high pressure fluid energy mill (104). The mill outputs a slurry comprised of particles of the material, the additive and the energy transfer fluid. The slurry is introduced into a hydrocyclone (310) for separating particles by size. The slurry is introduced into a spray dryer (108). The spray dryer atomizes the slurry, which falls through a heat zone, vaporizing the fluid. A collector (112) catches the dry falling particles.
