how to calculate critical speed of a ball mill

ABall Mill Critical Speed(actuallyball, rod, AG or SAG) is thespeedat which the centrifugal forces equal gravitational forces at themillshell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside amillasspeedvaries. Use our online formula Themill speedis typically defined as the percent of the Theoretical ...

    Effect ofMill Speedon the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. Themillwas rotated at 50, 62, 75 and 90% of thecritical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...

    In most cases, the ideal mill speed will have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts along the way. The ideal mill speed is usuallysomewhere between 55% to 75% of critical speed. Critical Mill Speed. Critical Speed (left) is the speed at which the outer layer of media centrifuges against the wall. Second Critical Speed (middle) is the speed at which …

    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. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
