The next step is to model the flow of water and mineral ore particles of different sizes through the mill i.e., the mass transport of the slurry and solids in the mill.The amount of energy transferred from the milling tools to the powder is significant and hardly measurable for processes in planetary ball mills. Thus numerical simulations based on a discrete-element-method are used to describe the energy transfer to give an adequate description of the process by correlation with experiments.
