what is the critical speed of ball mill

ball mill operating speed mechanical operations solved. 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 of15 rpm.Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed
