FIELD: process engineering.
SUBSTANCE: invention relates to ultra disperse grinding of multicomponent loose materials. Proposed device comprises two grinding tapered disks fitted to revolve in opposition of stationary base provided with channel to feed material into grinding zone, and annular casing to confine ground product intake chamber. Said intake chamber communicates with draft generator. Stationary support on the side of another grinding tapered disk is provided with additional channels to feed other materials into grinding zone.
EFFECT: no dust ejection into ambient air without sealing said grinder.
