FIELD: chemical engineering. SUBSTANCE: device has a housing, the distribution systems of the fluid medium and the granular material and a mixing device. The new feature of the device lies in the fact that the housing has the shape of a frustum and tores are placed in it. A band is passed through the central holes of the tores. One end of the band is wound on the reversible driving drum, the other one encompasses the last tore and is secured inside the housing. The innovation concerns the processing of the dispersed material. EFFECT: simpler design and intensified course of processing. 1 dwg
