FIELD: technological processes.
SUBSTANCE: invention can be used for dry and wet grinding of lump, grain and powder materials, as well as for making mixtures. Device comprises working reservoir 1, drive 4 for rotation of reservoir, rotating axis 2 arranged in working reservoir, pair of brackets 7, 8, first 9 and second 10 blades secured by means of levers 11 and 12 on brackets. One of brackets is immovably secured on axle 2 while another - with possibility of rotation. Brackets and blades are installed at angles where direction of incoming crushed material and grinding bodies, from first blade front surface crosses working reservoir inner surface for cutting edge of second blade. In blades there are through slots and/or holes extending from front to rear surface of blade. Minimum width of slots and holes is smaller than minimum size of grinding bodies.
EFFECT: higher efficiency of grinding and mixing and high level of dispersion of ground material.
