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 ...
Enter the width of amillshell liner. Note this is not the width of a lifter! You may use theMillLiner Effective Widthcalculationto determine this value. Themill critical speedwill becalculatedbased on the diameter (above) less twice this shell liner width.MillActual RPM: Enter the measuredmillrotation in revolutions per minute.

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 = 30.7rpm.But the mill is operated at a speed of 15rpm.Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.
In most cases, the idealmill speedwill have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many impacts along the way. The idealmill speedis usually somewhere between 55% to 75% ofcritical speed. Critical MillSpeed.Critical Speed(left) is the speed at which the outer layer of media centrifuges against the wall.
