For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R,,

At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground. Many early mines used stamp mills, but many operations today find that ball mills are more functional for smaller operations and perform well with the modern equipment we have available now such as combustion engines.
Zijin Mining Group has chosen an FL gyratory crusher, SAG mill and ball mill for the Majdanpek mine, part of the Chinese mining companys majority owned Zijin Bor copper mine, in Serbia.
