FIELD: chemical engineering. SUBSTANCE: device has a housing, the distribution systems of the fluid medium, the systems of charging and discharging the granular material and a mixing device. The new feature of the device lies in the fact that the housing is equipped with a branch pipe. A hollow cylinder with the expanding torus equipped with two radial holes and divided into cavities by the longitudinal partition is placed in the housing. The torus is mounted on the cylinder externally. The bands encompassing the torus from both sides and fastened on the cylinder surface by some of the ends are passed through the central hole of the torus. The other ends of the bands are wound on the driving reversible drums located in the housing. The innovation concerns the processing of the dispersed material. EFFECT: simpler design and enhanced efficiency of the device. 1 dwg
