The evolution of HPGR technology High pressure grinding rolls are preferred for their energy efficiency and flexibility in ore processing. Metsos unique take on this technology, the HRC HPGR, delivers even bigger as the most advanced high pressure grinding roll on the market.
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
High pressure grinding rolls HPGR are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer. Typical HPGR throughput rates range from 20 to 3,000 tph, with installed motor power as high as 3,000 kW per roll.
