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.
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.
The high pressure grinding roll machine comprises a pair of counterrotating rolls mounted in a sturdy frame. One roll is fixed in the frame, while the other is allowed to float on rails and is positioned using pneumohydraulic springs. The feed is introduced to the gap between the rolls and is crushed by the mechanism of interparticle breakage.
High pressure grinding rolls, also called roll presses, have been used in mineral processing plants [...] for many years, in the treatment of iron ore, copper, gold, diamond and various other ore types.

High pressure grinding is achieved by an advanced type of grinding roll. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls. KHD is an originator of this technology and has been successfully marketing HPGRs ...
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 ...
