Calculations: The critical speed of ball mill is given by, whereR = radius of ballmill; r= radiusof 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. Get Detail; formula for ball mill critical speed. The formula to ...
