Get Price01.01.2016· Such replacements lead to savings in capital expenditure in a plant design. The SAG mills have been mostly used for milling hard gold and copper ores with quartz, ultramafic or green stone as host rocks. The Bond work index of these ores ranges between 12 and 14 kWh/t. Subsequently, SAG mill application has been extended to softer ores, such as bauxite and clayey hard-capped gold ores.

Get PriceSAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency
