We investigated the effect of the friction coefficients of a barrel on grinding performances in a planetary ball mill. The linear velocity of chips, impaction and shear energy according to the friction coefficients were simulated by the discrete element method (DEM). The increase of the friction coefficient of the barrel not only improves the shear energy due to increasing the relative velocity between chips, but also reduces the impaction due to decreasing the average linear velocity of the chips. Finally, we validated the simulated result by measuring the removal amount of chips before and after grinding test and comparing with shear energy. The experimental results show the similar trend as the simulated results.
