Typical centrifugal mill includes a vertical cylindrical housing with feeding and discharging units. Separator with its built-in milling bodies is installed on a shaft coaxially with the housing. In conformity with a new design, the housing cap and separator are manufactured with axial passages; separator is designed as a multi-disc cassette (one, at least) rigidly fixed to the shaft. Roll-shaped milling bodies are placed between the discs on their periphery and are able to rotate and reciprocate in radical grooves of the discs.
