 High Pressure Grinding Rolls (HPGR) were introducedas a new grinding technology in ***4. Since then,they have been successfully installed in a large number of plants throughout the world, mainly for cement and limestone. More recently, HPGRs have also been applied in mineral processing plants,largely in iron ore and diamond treatment. In these industries, the application of HPGR ranges fromcoarse grinding, e.g. the grinding of *5mm (2.5”)size excess pebbles in AG circulation loops, to finalgrinding of <**0μm material to high Blaine values inthe preparation of pellet feed.
