FIELD: process engineering.

SUBSTANCE: invention relates to grinding and dispersion of materials. Proposed machine comprises housing, disc 2 and rotary disc 3 coupled with drive. Working surfaces of said discs have ledges 6, 7 and through slits made in radial directions there between. Machine comprises extra disc 5 arranged above rotary disc 3. Ledges of the latter are located between ledges at adjacent concentric circles of stator discs 2 and 5. Every of two working surfaces of rotary disc 3 is equipped with cutting device with curved blades.
