  • Autogenous and Semi-Autogenous MillsScienceDirect

     · A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al. is shown in Figure 9.6 where the pebbles from the SAG mill are crushed in the high-pressure grinding rolls. It is a general observation that SAG mills are helpful for grinding where wide variations in the grindability of ores are experienced.

  • Key considerations when selecting a mill lining system

     · SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes to protect the mill shell from wear caused by the impact and abrasion of the mill charge and to elevate and tumble the mill contents in the necessary manner to create a grinding action.
