The technology''s working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.
The use of high pressure grinding rolls (HPGR) is growing in iron ore processing. Because of the high technology of this kind of crusher, optimum utilization requires a thorough understanding of the effect of parameters on their operation. An important factor for consideration in the
High Pressure Grinding Rolls (HPGR) HPGRs are modern and efficient comminution machines, which are becoming more and more popular in mineral processing. In addition to the industryleading equipment that TAKRAF already offers to the mining industry, the TAKRAF HPGR is a benchmark in further developed comminution technology
High Pressure Grinding Rolls Crushing and grinding for ore and minerals processing Introduction High Pressure Grinding Rolls (HPGR) were introduced as a new grinding technology in 1984. 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

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.
With their excellent throughput capacity, low maintenance requirements and energy efficiency, High Pressure Grinding Rolls (HPGRs) are fast becoming a goto for greenfield projects looking to maintain their margins despite commodity price pressures and declining ore grades. In service since the mideighties and used primarily in cement production, HPGRs are increasingly being deployed as
