2.2 Rotation Speed Calculation of Ball Mill Critical Speed_ 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, %. There are many layers of ...
