List at least three reasons why SAG milling has become so popular over the past 40 years.Top point in the mill and load surface (H) [5-7]. This equation is profitable for determining of whole mill load volume which is included stony and metallic balls. Mill load ( ) = 113.7 - 127.3 H Dm (1) where H is the height of top of the balls to under the mills liners (m), and D.The mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.

Mainly in USA , the term circulating load is often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines it can be calculated by Coarse return TPH X 100 Mill output TPH.Normal range of cirulating load in a conventional close circuit ball mill is around 100-200 .An experimental laboratory scale ball mill available at the University of Lubumbashi was used in this research work. The ball mill measured 0.305 m in diameter and 0.127 in length. It was driven by an asynchronous motor rated with power close to 10 kW. A schematic of the experimental laboratory ball mill used is shown in Fig. 3.In FIG. 3, curve A illustrates a step change in the recycled material passing from the spiral classifier to the ball mill grinder device, and curve B illustrates the resulting change in the classifier motor load power P. Curve C illustrates a ramped change in the ore material recycle rate R from the spiral classifier to the ball mill grinding.
