the mill shell. Drive motors In the case of ring gear drives, either wound rotor induction motors or synchronous motors can be used. Induction motors Wound rotor induction motors are usually equipped with starters for a controlled ramp up of mill speed with modest inrush currents. Motor speeds usually require the appli-cation of a speed reducer.

Application 1. Grinding Mill Systems Grinding mills are crucial to mineral processing operations. As lower quality ore bodies are tapped, the tonnage processed per ounce of salable material will increase. This degradation in ore quality requires more power in the mill circuit, meaning larger motors and drives.
