Oct 19, 2006· 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.
