### Closed circuit ball mill – Basics revisited ScienceDirect

1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

### Cement mill Wikipedia

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

### Grinding control strategy on the conventional milling

Grinding control strategy on the conventional milling circuit With the increase in ratio set point, a decrease in Cyclone 1 particle size is required. This control loop will increase the water to the sump to cause a decrease in cyclone overflow particle size. Circulating load control The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution

However, the effect of each is difficult to quantify in practice as these two parameters are usually interrelated. Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill – cyclone circuit is around 250%. This value is used as
