In general, the SAG mill manufacturers will control the addition amount of medium such as steel ball at 28%, so that the capacity of semi SAG mill to process materials can be increased by 1030%. The SAG mill liners wear will increase by 15% due to the impact of medium such as steel ball during the SAG mill operation.

WhatsApp: +86 18838072829If you do not need a deep primary grind, a retrofit/conversion might be of value. A very high impact opportunity to increase your ball mill tonnage. A conversion is cheap in price as you can read in the footer. The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at 65,000 for a 13′ x 15′ mill.
WhatsApp: +86 18838072829The results showed that the HPGRball mill circuit achieved a 21% reduction in energy consumption over the existing SAGball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGRstirred mill circuit showed a 34% reduction in energy compared to the base case.
