Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron ore ...

simulation of ball mills using the DEM and SPH coupling. One of the newest works is related to Sinnott et al. [12], in which an overflow ball mill discharge and trommel flow has been simulated using the combined DEM and SPH method. The present work has some similarities and differences with that one as follow: in our simulation, we used
