    The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

    The discharge of each cyclone feed pump is piped separately to its own 15″ diameter cyclone, at a normal rate of 122 cubic meters per hour and 52% solids. Should both pumps shut down simultaneously, or the ball mill clutch be disengaged, the feed conveyor will be shut down. The cyclones separate the slurry particles by size; the coarse particles flow through the cyclone underflow to an ...
