critical speed calculation for ball mill
Mill Critical Speed Calculation
A smoothly lined mill consisting of 24 elements (walls) with 45 ball filling was simulated. The behavior of the charge was studied by changing the coefficient of friction at the wall. Three different disc sizes of equal proportion were used. The mill was rotated at 63 of the critical speed.
