Highlights Dynamic forces on a ball mill shell are extracted from a discrete element simulator. A method is developed to link shell forces to vibration signal of the mill shell. Experimental acoustic signal is compared to simulated one in time/frequency domain. This comparison provides a tool to evaluate the accuracy of the DEM simulator. Extending this work, forces in the mill may be ...
