The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
Roller press machines for pregrinding, semifinish amp; finish grinding For extreme efficiency and high equipment availability, look no further than roller press technology and products from FL. The roller press is a uniquely designed comminution tool, in that feed ore is exposed to extremely high pressure for a short amount of time resulting in a highly effective method of size reduction.

High Pressure Grinding Rolls (''HPGRs'') presently are seen as a standard technology to be considered in feasibility studies, as an alternative to be compared with more conventional crushing and
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.
High Pressure Grinding With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oillubricated cylindrical roller bearings.
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.

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 feeds density to 80% of its solid volume, exceeding its compressive
