  • critical speed formula for ball mill

    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. Therefore the mill is operated at 100 x 15/30.7 = 48.86 of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls and the other conditions
