Simulation of Size Reduction in Ball Mills and DEM The key problem here is that we can very quickly set up a simulation of a tumbling mill: the geometry and the motion are simple and the media are spheres! As soon as simulations start running, they look very lifelike The problem arises when we attempt to predict the productivity or
