The optimization of industrial grinding circuits has been successfully performed using mathematical models that describe the industrial scale data from breakage parameters determined in laboratory grinding tests. The test material studied here is a gold ore ground in a closed ball mill circuit with hydrocyclone classification.
Grinding ball production is a metallurgical operation and its quality is determined ... and where the problematic points are within a finish mill circuit. Simulation is the best tool to employ to improve the circuit performance if ... optimisation in a cement mill OCTOBER 2011 ICR XX ICR article draft.
A possible circuit change would send the crusher discharge to the ball mill circuit, better balancing the work between the SAG and ball mill. When ball milllimited and with low ore variability, a similar circuit modification redirecting flows can be done. It may be possible to redirect some of the ball mill hyrdocyclone coarse fraction back to ...

This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 µm). Furthermore, the operating capacity of the ball mill has reached 90% capacity, running at near full load.
