FIELD: technological processes.
SUBSTANCE: invention is related to devices for dry grinding of powdery materials and may be used in manufacture of construction materials, paint and varnish industry, preparation of activated bentonitic clays for oil industry and other industries that are related to application of finely dispersed materials. Device for activation of loose materials consists of loading bunker, vertical grinding chamber. Grinding chamber is made in the form of hollow cylinder, in covers of which shaft is installed with the possibility of rotation. Disks are fixed on the shaft, being connected by means of impact bars. On every disk fan blades are fixed for creation of opposite aerodynamical flow of gas suspension.
EFFECT: simplification of design and increase of device efficiency.
