MILL FOR MATERIALS FINE GRINDING Russian patent published in 2016 - IPC B02C17/20 B02C4/30 B02C2/00 

FIELD: ceramic industry.

SUBSTANCE: invention relates to very hard brittle materials crushing devices and can be used for production of ceramic materials micro powders, pigments, fuel additives and other materials. Mill comprises closed housing with branch pipes 1, 2, respectively, for product inlet and outlet, cylindrical working chamber 3 with inner lining 5 and arranged in closed housing and having outer water jacket 4, and vertical rotor in form of shaft 6 and connected to it horizontal bearing discs 8 connected with rotary drive 7. Vertical rotor is installed in working chamber 3 along its axis. On support plates 8 by means of rotation axes 9 grinding elements 10 are fixed, which center of gravity is shifted relative to axis of rotation. Grinding elements 10 are made up of metal body and fixed on it grinding insert, which at element rotation contacts lining 5 surface. At that, working chamber grinding inserts and lining are made of ceramic composite material, with content of diamond 20-75 vol%, silicon carbide - 20-75 vol%, silicon - 3-40 vol%.

EFFECT: mill is characterized by increased service life and wider area of application.
