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
The grinding elements are two counterrotating rolls, between which the material is crushed. One roll is designed as a fixed roll and the other one as a floating roll. The required comminution pressure is transmitted via the floating roll. The highpressure interparticle comminution produces compacted cakes of material
high pressure grinding rollers. 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
