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. In the other side of my shafts there are two 40 mm,Mill Critical Speed Calculation,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.Ball Mill Critical Speed | Crusher Mills, Cone Crusher,,Ball Mill Critical Speed Formula – Raymond Grinding Mill.,Working of Ball Mills. MIKRONS Ball Mill form a and ball mills usually operate at 65% to 75% of the critical speed.,Consequently, it has proven best to describe the speed instead of referring to their percentage of critical speed as is done for ball mills of the same diameter.
