Grinding Operation  an overview ScienceDirect Topics
A mill ready to start a grinding operation could be around 150 t in dead weight. Thus, the initial torque on the mill shaft is very high and an electric drive motor and drive is designed to cope with it. Figure 8.11 illustrates a typical change in torque with increasing speed of motor. It can be seen that the peak torque of 140% of the running ...
