The high pressure roller crusher is also called roller crusher or roller press. The significant difference of high pressure roller grinding compared with compaction is that the press forces between the rollers are lower because no new adhesive forces need to be created. Get Price
High-pressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing ... The application of roll press technology to high-pressure comminution achieved throughput rates that were equal to or better than those produced with conventional equipment.
High Pressure Grinding Rolls (HPGR or Roller Press) These grinding circuits have recently been developed. These are pre-grinding, hybrid grinding, semi-finish grinding and finish grinding. The pre-grinding system is applied if a production increase of 20 – 30 % is required.
In a high-pressure roller press, two rollers pressurize the material up to 3,500 bar, improving the grinding efficiency dramatically and significantly reducing energy consumption. High-pressure roller presses are most often used to expand the capacity of existing grinding mills, and are found especially in countries with high electricity costs or with poor power supply.
