MILL Russian patent published in 2013 - IPC B02C13/14 

FIELD: process engineering.

SUBSTANCE: invention relates to grinding-dressing equipment for grinding of minerals. Proposed mill comprises frame and crossbar, top rotor with lateral sieving surfaces and top loading openings. Rotor houses post and post jacket, bottom rotor with radial ribs, bearing assemblies and V-belt pulleys, drive motor and intake bin.Mill accommodates extra shaft thrusting by one end against bearing assy and by opposite end coupled by half-coupling with drive motor. Gear ratios of articulation of top and bottom branches of the loop composed by extra shaft, drive and driven pulleys of top branch with appropriate V-belts, drive and driven pulleys of bottom branch with appropriate V-belts are not equal.

EFFECT: power savings owing to circulating power in closed loop.
