SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill
Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009)

SAG mill product feeds two parallel ball mills of 6.6 m 11.1 m (internal diameter length), each with a 9.7 MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of

Small amounts of costs for maintenance can prevent the mill from far reaching breakdowns and a huge financial damage. Besides, regular maintenance on machines also decrease spare part and service costs. We can diagnose many problems in the mill at early stages thanks to maintenance. One of the first things to examine when a mill is experiencing
