Ball Mill Parameter Selection & Calculation Power

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, %.

of autogenous, semi-autogenous and ball mill grinding circuits[6]. Schnatz carried out a huge test program on a semi-industrial ball mill which operates in a closed circuit. He evaluated performance of a ball mill circuit by varying the L/D ratio, ball charge filling ratio, ball size and residence time and determined their optimum value[7].
