In order to investigative the effect of mineral particle shapes to breakage rate of ore, basing on discrete element method, comparative grinding experiments were performed separately in a laboratory ball mill under the same conditions of mass and feed by using regular tetrahedron, parallelepiped and sphere as models of mineral particle. This study shows that ore grain shapes have a great influence on breakage rate due to different impact energies in ball mill.
