FIELD: process engineering.SUBSTANCE: invention relates to open working of minerals, peat and medical-peat deposits, mainly, in frozen state. Proposed plant comprises auger with cutting tool fitted thereat and planetary gearbox, said auger being fitted in casing with ledges on its inner surface. Said casing is driven be planetary gearbox in direction opposite that of auger at transfer of torque to auger and to outer casing from one drive. Casing ID is 1.5÷2 times larger than that of auger. Casing inner surface accommodates helical groove with winding direction opposite that of auger helical winding and with helical drove inner edge gap relative to cylindrical surface constricting auger outer edges. Said casing incorporates cutting edges.EFFECT: higher machine efficiency.2 cl, 2 dwg |
