  • Increasing availability through advanced Gearless Drive

    Variable speed allows to compensate for throughput changes as well as for harder ore, and to prevent meta-to- metal contact between the grinding media and the mill lin- ers. This leads to optimized operation and significantly less wear to the mill liners and ball consumption, as explained by a concentrator's operation and maintenance supervisor in the US. Furthermore, the mill
