Having proved its success in energy efficiency, the High Pressure Grinding Rolls became widespread all over the world in many plants. The first application of the HPGR was in 1985 in a cement plant, mainly for capacity improvement purpose. Then various circuit configurations were derived to achieve reduction in overall specific energy consumption by transferring more of the grinding required to the HPGR. By mid 1990s, HPGR installations have been used in minerals industry. The HPGR was introduced to minerals industry as a replacement for tertiary crushers, SAG mills and rod mills. In some applications it appears as a pebble crusher in AG milling.
