As semiautogenous (SAG) mills become increasingly larger in size, the design of SAG mill liners has been more and more important, and the appropriate liners would enhance mill efficiency and performance. The replaceable liners are mounted inside the mill and exposed to media and/or the material being ground.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

SAG Mills use a combo of ball milling and autogenous (letting the material crush itself) milling. They do have balls in them, but usually less of a load of them (820% load) than a ball mill (typically around 30% loaded). They also have plates on the inside that lift the load up and tumble it, like a dryer does.

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,, van der Westhuizen,, Mainza, 2009). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.

However, the SAG route is more powerintensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has become available in the form of high pressure grinding rolls (HPGRs), which can replace the third stage of crushing and also the SAG mill.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
