The 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
