摘要：
We present a method to predict how grain size distribution (gsd) evolves during confined comminution. We describe particle breakage as a probabilistic phenomenon considering the single particle strength and the pdf of inter-particle contact forces from DEM simulations. Our results show a good agreement with published experimental data.
