put. Larger mills have a low energy efficiency, hence costly to operate [5]. Ball mills operate by movement and interac-tion between the grinding media and the ore to be broken [6]. According to Hassanzadeh [7] about 37% of the costs are used for grinding media only,13% for liners and about 50% is used for energy.
