    Ball MillParameter Selection – Power, RotateSpeed, Steel

    Aug 30, 2019· When the ball mill cylinder is rotated, there is no relative slip between the grinding medium and the cylinder wall, and it just starts to run in a state of rotation with the cylinder of the mill. This instantaneous speed of the mill is as follows: N0 —- mill working speed, r/min; K’b — speed ratio, %.
