FIELD: construction engineering; device for grinding and preparation of building mixtures. SUBSTANCE: grinder- mixer has housing, motor, planetary drive in form of two cylindrical differential gears, crushing chamber with loading and unloading bins and working member made in form of cylindrical spring, rotary compressor and centrifugal regulator. Grown and sun gears are interconnected in pairs. Carrier of output differential gear is kinematically linked with centrifugal regulator. Working member is rigidly connected with sun gear cluster. Crown gear cluster is linked with compressor blades. Compressor outlet main is connected with outlet cavity of crushing chamber. Centrifugal regulator is kinematically linked with damper of loading bin. EFFECT: enhanced operational reliability. 1 dwg
