The technology's working principle is that two counter-rotating 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. Feed material can be ...
High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production. Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock. However, they can also refine softer materials like industrial minerals. The smaller models of the HPGRs are particularly productive in producing manufactured sand for ...

With ever increasing electricity costs substantial effort is being made to reduce energy consumption. While incremental savings have been made in several areas, it has been many years since there has been a breakthrough development in crushing and grinding. The last major development has been high pressure grinding rolls (“HPGR”), first used in 1985 in a cement plant. HPGR are used as a ...
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.
The technology's working principle is that two counter-rotating 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. Feed material can be ...
POLYCOM® high-pressure grinding roll The reliable and energy-saving grinding system One of the principal reasons for the outstanding success of the high-pressure grinding roll in the cement industry is its low power requirement. Today, this mill is employed all around the world for the grinding of cement raw material, cement clinker and granulated blast furnace slag. For new plants, the ...
High Pressure Grinding Rolls (HPGR) technology is accepted as an energy-efficient and cost-effective alternative for treating specific mineral ore types. HPGR technology has been advancing within ...
Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid volume, exceeding its compressive strength with equal pressure being applied to ...
