Abstract/Summary The kinematic data resulting from 3D particle tracking experiments of a typical bulk charge particle is used to derive an empirical power model that forms the basis for comparison between the DEM and experiment. The model is derived from the center of circulation coordinates and given as a function of mill speed. The wide range of milling configurations coupled with experimental trajectory data accurate to within 0.15 mm in spatial resolution ensure that the comparisons are robust. The power prediction from both the DEM and experiment is done for a 142 mm diameter mill of the same length and charged with 4596 particles with a mean diameter of 6.1 mm.
