  • ball mill operating speed mechanical operations solved

    Calculations: The critical speed of ball mill is given by, whereR = 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
