A laboratory scale ball mill (D x L = 203 x determination of the work index for ball and rod mills in 250 mm) with a charge of 19 and 25 mm steel balls 1952 and modified it in 1961. The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load.

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...
