METHOD OF PROCESSING OF MATERIALS Russian patent published in 1998 - IPC

FIELD: grinding of ore and rock products. SUBSTANCE: the method consists in feeding of material with water to the cyclic area of grinding from the top, volumetric compression of material in the grinding area, fretting of material particles at a simultaneous impulse action on particles at the instant of their deformation and destruction by a high-temperature liquid flow, superheated vapor or hot air, mixing of the ground product with cold water and removal of pulp from the bottom; feeding of material with water or solution of surfactant to the cyclic grinding area and mixing of the ground product with water are accomplished after a preliminary electrochemical machining of water or surfactant fed in the process of grinding in an electrolyzer, impulse action on material particles is accomplished simultaneously with feeding of oily substances and surfactants. EFFECT: facilitated procedure. 2 cl, 3 dwg
