Contact SupplierCalculations: The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed.

Contact SupplierThe torque and time requirements of the mill with the ball charge will set the magnitude and time of the inrush current during mill starting. The inertia for this mill reflected to the motor shaft is calculated to be 24,300 ft-lbs2. The time to accelerate the mill to the design speed is given by the following calculation: Time = WK2x Speed Change

Contact SupplierEffect 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. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4.
