FIELD: process engineering.
SUBSTANCE: invention relates to fine grinders and may be used in construction, mining, chemical industry, etc. Proposed mill comprises housing composed of vertical cylindrical container suspended via links to support frame. Said frame is engaged with drive and divided by diaphragms into chambers with milling bodies. Besides, said mill incorporates three identical cases composed of vertical cylindrical containers to make integral unit of four cylindrical containers arranged at right angle to each other. Every case is suspended to support frame via three links arranged regularly in circle. Housing top and bottom have journals fitted on vertical axle to carry thrust rolls fitted therein, Drives of all cases comprises vertical drive shafts and overrunning couplings and are engaged sequentially and in pairs by stiff kinematic linkage to make kinematic synchronisation system to time circular vibrations of every pair of cases.
EFFECT: higher stability and reliability.
