The ball mill modelling scheme using an ore specific breakage distribution function in a multisegment ball mill model has provided an adequate representation of industrial ball mill performance. Fur ther work to extend this technique to ball mills less than m in diameter and to mills operating at different process conditions is in progress.

size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 monosizes namely 8 mm + mm, 4 mm + mm and2 mm + mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was
