-1/2, where n is mill drum rpm, D is drum diameter, m, drum electromagnets excite magnetic pulses there inside. Note here that at displacement of electromagnets from 0° making the origin of angular coordinates at intersection of horizontal diameter left end with the drum to 30-50° to ensure increase in fall speed of ferromagnetic lumps at acceleration a, to be summed with gravity acceleration g. Magnetic pulses in the drum are eliminated in sector from 30-50° to 70-110° to resume the motion of balls and stock grinding by abrasion and crushing. Magnetic pulses are excited in section from 70-110° to 180° to trap ferromagnetic stock to be lifted to 180°. Magnetic pulses in the drum are eliminated in sector from 180-0° to deliver stock by friction and inertia to coordinate 225-226°. Another portion of stock is accelerated by magnetic pulses in sector of electromagnets of 0° to 30-50°, electromagnets being transferred the mill right to left. Horizontal components h of acceleration make ferromagnetic lumps crush the stock at 90° and move over lining of the pole and stock layer formed earlier.;EFFECT: higher efficiency of grinding."/>
