3. Role of DEM in advanced mill modelling A major advance in the modeling of ball mills became possible through the development of the discrete element method. DEM provides a numerical procedure for solving Newton’s second law with an appropriate contact relation-ship that can be applied to describe the motion of each

An investigation was conducted to determine the effect of the ball diameter sizes on milling operation. A laboratory 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 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm for the experiment.
