Understanding the full potential of installed plant equipment and identifying the factors causing the of limitation on a grinding circuit should be two major priorities when it Cities to optimising a minerals processing Partial secondary crushing has enabled h full utilisation of the available installed ding power, with an optimum split of power between the SAG and ball mills increasing the grinding circuit throughout by about 45 percent. By comprehending the ore breakage characteristics-as well as using comminution circuit modelling-the benefits of SAG mill feed size manipulation can be readily accessed. These were some of the findings made by Australian-based Orway Mineral Consultants after it carried out a case study on the design and implementation of a partial secondary crushing circuit used to increase milling capacity at Equigold NL's Mt Rawdon gold mine in Queensland.
