Ball Mill Simulation With 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.
