The discrete element method has been used to simulate the particle flow in a ball mill under different operating conditions. The model was validated by comparing the simulated results of the flow pattern and input power with those measured from a same-scale laboratory mill.

The emergence of the discrete element method (DEM) allowed simulation of charge motion in tumbling mill. In the last eight years, the DEM for simulation of tumbling mills has advanced sufficiently that it has become a very practical tool in the mining industry. This manuscript gives an overview of the DEM as applied to the tumbling mill problem.

Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials. They have been used for decades in the production of fines and in the final stages of ore comminution, where optimal levels for the enrichment particles’ sizes are obtained. Even though these ubiquitous machines of relatively simple construction have been subjected …

The discrete element method (DEM) is a proven numerical technique for modelling the multibody collision behavior of particulate systems. This method is used here to study the motion of ball charge in tumbling mills. To get meaningful results, it is essential that the parameters involved in the model be carefully determined.
