Abstract: The study describes the study of the effect of liners height and step in ball mills which has been conducted using EDEM Software by DEM Solutions. Digital models of ball mill liners with various profiles using the NX CAD Software by Siemens PLM Software have been built. EDEM Software has been used to calculate kinematic and energetic parameters of a grinding media. The graphic and digital models of grinding media motion have been prepared their comparative analysis has been conducted; the rational operation mode of the mill has been showed. The properties of materials that a lining and grinding media are made have been considered when calculating the motion of grinding media. The interaction between grinding media and the lining has been characterized by coefficients of restitution, static and rolling friction and by variable height of the lifters, step of the lifters and rotation frequency of the mill drum.
