Mill relining is the most specialised maintenance task in a mineral concentrator. Almost invariably the AG, SAG and Ball mill liner lives dictate the shut-down dates of the concentrator. The replacement of the mill liners determines the length of each concentrator shut-down.
AG/SAG Mill Power. In designing crushing–grinding flow sheets, correct estimations of mill power draw are important as it serves as one of the deciding factors for selecting an option between AG/SAG mills. In most cases, the circuit with the least or optimal power consumption is the preferred choice.
Leading the world in ore hardness testing. The SMC Test® is the most widely-used comminution test in the world for AG & SAG Mills, HPGRs and Crushers. It is used to design comminution plants, optimize circuit performance, forecast throughput, reduce CO 2 emissions and cut energy costs. Read case studies.
AG and SAG mills can be designed for dry or wet grinding. The bearings are hydrostatic slide or slide shoe bearings. Usually, AG and SAG mills have a gear rim/pinion or direct drive. Our p rodu ct portfolio includes sizes from a laboratory scale to a diameter of 10 meters or more. For transport reasons, these mills consist of several flanged parts.
The AG/SAG mills can be operated in open or closed circuits. However, even in an open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally. In many recently designed plants, the traditional three stages crushing followed by rod ...

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.
of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills. This product slope averages less than 0.5 when plotted on log/log paper and therefore contains an extra amount of ne material fi compared to a PSD, having a 0.5 slope. This fi ne material,
