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.
Apr 14, 2012· In one textbook, it says that the critical speed is the minimum speed at which an object can complete the circular motion. It gives the formula: v = square root of (g*r) However, in another textbook it says that the formula is: v = square root of (2*g*r) How can there be two different types of ...
