A broken liner, which is particularly severe for large AG/SAG mills, can arise from media impacting directly on the mill liner. Multotec's rubber mill linings are designed by combining the results of computer simulations and inspection data in order to optimise charge trajectory and wear life. The mill liner components are available in a wide ...

same conditions apply in sag mills. However, in this case the required balance between coarse and intermediate size rocks is different to that for ag mills. This is because the steel balls in the sag mill do the duty of the larger rocks. As a result the more balls that are loaded into the sag mill the fewer larger rocks are required.

Ball mill: When the particle size of the product is less than, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.

Semiautogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diametertolength ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These

The model has been validated against experimental results that were obtained from an industrial SAG mill. The SAG mill is lined in two rings each consisting of 60 rows of rail type liners. The liners are cast chromemolybdenum steel with an average Brinnell hardness of 350. The mill operating conditions and geometric specifications are given in ...

As the SAG mill enters a stable operation state, the grinding system's charging behavior in the PHSP and SP grinding systems is different. As shown in Fig. 9, the shoulder and the head in the SAG mill containing polyhedral ore particles are slightly higher than that of the SAG mill containing only spherical particles.

performing SAG mill. It is possible in some cases to modify a SAG circuit to force it to perform better, but this often takes time, much effort and costly modifications. In most cases the capital spent on a properly sized SAG mill may prevent production losses that would be many times greater over the extended start up period.
