A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The SAG mill has a trommel on the discharge end of it. Oversize is returned to the mill by a bucket wheel and water jet. Trommel undersize was pumped to a vibrating screen where the screen oversize was sent back to the mill and the undersize was pumped to the cyclone circuit. Figure 2 shows the flowsheet for line 2 with only the trommel,

The OED Mill delivers the highest possible discharge capacity by eliminating the need for pulp lifters; instead, material is discharged directly through the grates, solving the throughput bottleneck problem often associated with comminution circuit design. The pursuit of high-efficiency pulp discharge systems by mill and liner suppliers is a testament to the potential upside of open-ended milling.

The SAG mill generated much more fines than the modelling indicated and this had detrimental effects on copper recovery in the flotation circuit. With the overgrinding in the SAG mill, and the circuit being SAG mill constrained for throughput rate, options to coarsen transfer size were investigated. Throughput rate was improved by increasing the transfer size from the SAG mill to utilise ...

"Many SAG mill liner designs perform very well in their objective to achieve the desired particle size and protect the mill structure. However, no matter how well a mill is operated, and no matter how well a liner design performs, a mill is only as good as its ability to discharge the slurry out of the mill.

SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries.
