"Rolls are not suitable for the treatment of highly weathered ores or feed con-taining a large proportion of fines or moisture". HPGRs are used in the diamond industry for treating soft, sticky material containing up to 16% moisture; and in the iron ore industry for the preparation of pellet feed (< 100 µm) containing up to 12% moisture.

High Pressure Grinding Rolls (HPGR) technology is accepted as an energy-efficient and cost-effective alternative for treating specific mineral ore types. HPGR technology has been advancing within manufacturing facilities and research centers since its first installation in 1985. Over the last three decades much of the literature on HPGR have focused on the industrial applications and …

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.

The maximum CI of HACS-FL complexes was 59.36% at the feed moisture of 40%, and then it decreased to some extent when the feed moisture exceeded 40%. This phenomenon suggested that proper feed moisture (30%, 35%, and 40%) promoted the combination of starch and flax oil, while excess water prevented the formation of complexes.
