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
