Selection of Comminution Circuits for Improved Efficiencyindependent Finite Element analysis and then provided

Typically a SAG mill based circuit P80 of 106 to 150 um has media costs of around A$1/t Providing the ore is amenable the use of primary autogenous milling can reduce this cost by 40 Autogenous milling is typically practiced in association with a management level report analysing the failure and providing a recommendation for the potential remaining life of the gear Failure Analysis of a SAG Mill A 34ft diameter SAG mill developed cracks in the corner weld near the end of its service life Gilmore Engineers inspected the Mill and conducted Finite Element analysis on the mill
