A worn surface is depicted in Fig. 10 a and c. Consistently, a high pressure, respectively a specific grinding force of 6.4 MPa, was set to outweigh abrasion by indentation (microfatigue) as the dominant wear mechanism (see corresponding Fig. 10 b and d). The turning speed of the rolls was kept constant.

Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
