Optimization of mill performance by using

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

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 ftlbs2. The time to accelerate the mill to the design speed is given by the following calculation: Time = WK2x Speed Change
