However, for ball milling, the mixed ore is characterised as moderately soft to abrasion resistance, while the Sulphide ore is considered soft in ball milling. For this study, emphasis is placed on the impact breakage resistance dominant in SAG milling. Since commissioning in 2008, the 32ft SAG mill processes mostly Sulphide ore, and occasionally
For design purposes, you need an estimation or prediction of your SAG Mill's tonnage; well, there are 3 ways to generate good rock "ore" hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three "faiths" of grinding, and there are small-scale tests …
The Mawby Memorial volumes [15,18,19,20] provide a useful record of the evolution of large SABC circuits as they gained acceptance from the early adoption of very large ball mills at Bougainville Copper to the rise to dominance of SAG mills and to the uptake of very large (20 MW) SAG and ball mills at Cadia and other sites.
Indeed, in four to seven weeks of operation, a SAG-ball mill circuit can consume the same weight in steel used to construct the entire milling circuit structure. Improving the wear life of mill liners is one way to tackle indirect energy consumption; it also improves mill productivity as downtime for liner replacement is reduced.
