### Simulation of Size Reduction in Ball Mills and DEM

The mill (with 30 cm in diameter and 30 cm in length) and the test conditions are standardized, with a maximum ball size of 40 mm and an ore top size of 3.35 mm. With less than 300 balls, it poses no challenge in running the simulations, if only grinding media are included. For such a small mill, one could also include the ore or powder charge.
