METHOD OF PROCESSING COAL TO POWDER AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 1996 - IPC

Abstract RU 2062951 C1

FIELD: range of energetics for coal procession. SUBSTANCE: by feeding inert pressurized gas before pressure release from sluice to upper part of hopper first stage of pressure release with separation of coal from pressurized gas after it outlet from the sluice of pressurization and with feed of cleaned gas to near-bottom part of accumulating hopper is performed in such a way, that the above mentioned first stage of pressure release occurs in larger part of inert gas. EFFECT: enhanced efficiency. 8 cl, 1 dwg
