Comminution '08 Tavares moved ball mill modelling to a new level with his application of nonlinear breakage rates. He introduced two distinct modes of breakage, body and surface damage, and demonstrated how to incorporate them in a ball mill model by using particle bed breakage tests and DEM modelling of the energy distribution. Such studies must surely
