CENTRIFUGAL MILL Russian patent published in 2009 - IPC B02C17/08 

FIELD: engines and pumps.

SUBSTANCE: centrifugal mill comprises grinding bodies and crushed material placed into milling drum fixed on dynamically movable yoke, which is connected via bearings to crankshaft cams. Crankshaft rotates in main bearing of mill bearer frame, with mass of mill movable parts that vibrate along circular trajectories in plane perpendicular to drum axis, and reactive moment of workload balanced by balancing device. Mill is equipped by additional milling drum, and crankshaft is matched with center of gravity of dynamically vibrating system "yoke-milling drums" and stabiliser of spatial position of dynamically vibrating system of "yoke-milling drums". Stabiliser is fixed with their one side to yoke, and with the other side - to mill bearer frame.

EFFECT: increase of design strength, reliability and durability of mill with simultaneous simplification of maintenance, lower metal intensity, reduction of manufacture cost.
