The grinding mill might be the issue. Of course, the hydrocyclone isn't the only place to look when you are reviewing the classification of your grinding mill circuit.. Often when we're investigating a mill circuit, there are cases where the amount of new feed to the plant has exceeded the ability of the mill to grind the ore fine enough to allow the cyclones to generate …

The purpose of a grinding mill is to convert electrical energy into rock breakage. The best use of that asset is to try to maximize the power draw. Try to hold the mill speed high and vary the feed rate to hold the weight (or bearing pressure), but watch out for "cycling" or "surging" that indicates instability in the charge.

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.
