tion in mineral processing, both for its relevance to the downstream processes as well as for the high costs associated with the energy consumption. Comminution is generally the single largest consumer of energy on a mine site, accounting for an average of a 53% (CEEC the future, 2012). The average grade of ores is falling in most places in the mining industry, resulting in even higher costs ...

Get Price#### Key considerations when selecting a mill lining system

· SAG mills usually have a larger diameter than length and are used to reduce large feed size ore (typically ~300mm) down to ~3mm, often for further grinding in a secondary process. Ball mills are smaller in diameter than length and can be used in either primary, secondary or tertiary grinding appliions to reduce material from ~20mm to very fine product sizes measured in microns or mesh.

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...
