The aim of the ball mill/ hydrocyclone circuit is to produce the optimum flotation feed particle size while maintaining grind throughput. The optimal operating point is a tradeoff between throughput, recovery, and grinding cost. Copperton has recently focused on the role of the hydrocyclone battery and how to monitor the performance of each

The most common secondary mill is a ball mill in which relatively fine feed particles ( mm top size) are ground in a charge consisting predominantly of steel balls. Mills can be operated in open or closed modes (which refers to whether the product is size separated in some way with the oversize fed back into the mill).

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

Ball mill transport index control strategy. A simple ratio controller was implemented to regulate the solids content in the mill by manipulating the feed water. A calculated percent solid index is used to monitor the transport in the ball mill. A separate study was initiated to develop a measurement of this property (Bascur, 1985).
