At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls all the other conditions remaining the same Calculations The critical speed of ball mill is given by where R = radius of ball mill r = radius of ball. For R = 1000 mm and r = 50 mm n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm.

Ball mills account for the majority of all mills in cement plants and therefore the optimization of established ball mills implies high savings potentials. Parameters that hold potential energy savings are load level revolution speed combination of the ball charge lining design and the adjustments of the separator. Standard optimization methods include meter sampling of the effective length
