FIELD: process engineering. ^ SUBSTANCE: invention relates to crushing rocket solid propellants and powders aimed at processing into explosive mixes or boiler fuel. Proposed device is made up of machine, water bath, multi-saw unit consisting of, at least, one set of saws arranged partially or completely in said water bath. Proposed device includes assembly to control grain feed rate by axial feed mechanism. Multisaw unit is provided with device to correct saw clearance subject to grain diameter, size of its central bore, grain feed arte and rpm of said saw unit made up of telescoping bushes. Said machine comprises two rolls running toward each other and provided with set of sharpened pins arranged on roll cylindrical outer surface to mince grains of solid propellant. ^ EFFECT: simplified design and process. ^ 8 cl, 3 dwg |
