When HPGR is used in combination with ball mills or as a standalone grinding device, it offers benefit such as fineness, improved throughput, and quality of the ultimate product in iron ore pellet feed preparation. The HPGR comminution solution is anticipated to show tremendous growth owing to its better liberation of large, rare and highvalue diamonds, as well as small ones, with minimal damage.

High pressure grinding rolls (HPGRs, also known as roller presses) are becoming well accepted for coarse, abrasive, and hard rock applications. When the first HPGR for coarse ore was commissioned at Los Colorados in 1998, there were only 14 HPGRs installed in the minerals industry, mainly for grinding pellet feed to increase the Blaine value (Van der Meer et al., 1997), and only three KHD HPGR
