Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or classifier (classification system) are screened and the cumulative weight percentage retained is calculated for several mesh sizes to obtain the Ball Mill Circulating Load. The percentage through the smallest mesh can also be used to determine Rcl, as follows:

In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent. It may appear strange at first sight that the circulating load between a mill and classifier producing, for example, 100 tons of finished product per day can be as much as 400 tons or more, but this will be ...

The circuit consists of a two compartment ball mill and a dynamic air classifier. There is a slotted diaphragm inside the ball mill that separates the two chambers from each other. The particles coarser than the size of the slots (10 mm) stay in the first chamber while the finer particles pass the second chamber for further size reduction.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
