Oct 19, 2006What 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.
