wear to the mill liners and ball consumption, as explained by a concentrator's operation and maintenance supervisor in the US. Furthermore, the mill's direction of rotation can be simply changed with a switch, so that the wear on the liner is distributed equally at both sides. Reduced wear of the liners prolongs the mill maintenance intervals.

A ball mill is a type of grinder widely utilized in the process of mechanochemical catalytic degradation. It consists of one or more rotating cylinders partially filled with grinding balls (made ...
Control, Process Data Preventive Maintenance. DCS or SCADA systems control many SAG, rod, and ball mills. These systems are diverse and individualized depending on the equipment and the scope of the system installed. Sometimes you'll see simple metrics, like run status, and other times you'll see more specific metrics like flowrate or RPMs.
