What it is the optimun speed for a ball mill posted in Pyrotechnics I have done a ball mill , recenly finished , but the motor has too rpms , is too fast for use in a ball mill the pvc cylinder that i use , left of the shafts. With the motor i will use a 40 mm pulley , because i have a 50 mm driven pulley, in one of my two shafts.

Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90 of the critical speed. Six lifter bars of rectangular crosssection 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
