AMIT 135: Lesson 7 Ball Mills & Circuits – Mining Mill Operator Training
Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40 K√F dB = ball size (cm) F = feed size (cm)

Ball Mill
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol

Effect of ball and feed particle size distribution on the milling
For the feed sample sizes investigated, the three ball mix was more effective for the coarser feed due to the presence of the 50 mm balls whilst with a finer feed the binary mix gave the optimal amount of size class of interest. These results prove that a close control of feed and ball match is of paramount importance if one is to improve the efficiency of milling circuits.
