Trends in der Minenindustrie
Instead of conventional AG/SAG and ball mills, processes only with high-pressure grinding rolls (HPGR) and vertical mills (Fig. 5) or other combinations of mill types are employed in practice. Besides a pure grinding feed, a crucial aspect is the optimum energy utilization in beneficiation for the respective types of ore and applications.

Autogenous and Semi-Autogenous Mills
A typical SAG-HPGR-Ball mill circuit suggested by Patzelt et al. [6] 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.
