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. Besides, proposed device comprises centrifuge to separate solid and liquid phases. Said machine comprises two rolls rotating toward each other, blower arranged there above to force hot AIR in clearance between rolls to dry mincing plates and rule out sticking of minced particles to roll surface. Water is cleaned by circulation system consisting of, at least, two preliminary and final cleaning tanks equipped with water cleaning gauze filter. ^ EFFECT: simplified design and process. ^ 8 cl, 3 dwg |
