N2 - This paper proposes an analytical model to assess the evolution of the grain size distribution due to crushing of granular materials during cyclic loading. The model, that requires very low computational cost, is based on the theory of polydisperse mixtures proposed by De Larrard, 2000 and the theory of Markovian processes. The evaluation of the performance of the model was carried out experimentally using a gyratory compactor and numerically using a discrete element model that includes crushing. The comparison of the results obtained experimentally with those obtained using the models, numerical and analytical, shows very good agreement. For this reason, the analytical model proposed here is a useful alternative to be included in a model based in continumm mechanics.
