This work shows the application of a new breakage model fitted using discrete element method (DEM) simulations in laboratory scale, which are used to model the bead motion inside the planetary ball mill and also to estimate the energy generated and distributions of particles of a dry powder. Thus, the same material can be fitted to various experimental tests with varying calibration. The simulations results showed that charge throw trajectory was more susceptible to mill speed. Hence, the contact parameters revealed negligible effect on grinding dynamics.
