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 The GMD is also known as “wrap-around motor” or “ringmotor”. Almost 25 years later, the first GMD with 12.0 MW power and 13.0 rpm was installed in the minerals industry. Since TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS
