decreasing the impact force available through lowering the mill speed. Likewise, if the circulating load is low and the product too fine, even with a high ball charge, the circuit selection may be incorrect. If a recycle crusher was not included it should be trialled. If included, the use of a single stage mill is likely to be inappropriate.
