Grinding Circuit Overload - Grinding & Classification ...

Another common issue with SAG mills is operating at very low density (e.g. <70% solids) - if there is room to increase SAG density, this will enable the SAG to grind finer with little or no decrease in throughput. Consider reducing the feed rate when the overload starts rather than waiting until a grind-out becomes necessary.
