FIELD: means of separation.
SUBSTANCE: invention relates to the means for self-grinding and separating various solid materials. Device for the separation of loose materials contains two grinding concave aerodynamic wheels, which are mounted coaxially on the fixed hollow axis with the hole for supplying the starting material. One of the aerodynamic wheels is mounted with the possibility of rotating relative to the other stationary aerodynamic wheel. On the rotating aerodynamic wheel in the central part inside the working chamber there is the dynamic injection impeller, which is made in the form of the Laval nozzle with the internal elements in the form of injection and accelerator blades.
EFFECT: invention allows to protect the bearing assemblies from dust and improve performance.
