The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond, 1962).

• Uses the changes in the mill load and power to automatically detect whether the mill is overloaded or underloaded. • Uses . safety controllers. to change the solids feed rate and feed water to prevent mill overloads. • Estimates the power load curve and optimum load. By optimising the mill power usage and preventing mill overloads,
with different circulating loads, the Bond work index is higher with lower circulating loads. The purpose of this study to determine the effects of circulating load (CL) and test sieve size (P;) on the Bond ball mill grindability (Ght,) and work index (W,) with natural amorphous silica. 2 MATERIAL AND METHOD
The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (W i).This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained.
