High Pressure Grinding Rolls (HPGR) Summary Machine for energyefficient comminution between high pressure grinding rolls (HPGR): The principle of particle bed breakage is known to be more energyefficient due to particleparticle breakage. It is a good practice example of how an invention arises from academic research and becomes an innovation.
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 rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.

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.
Why your High Pressure Grinding Roll needs to skew . Why your High Pressure Grinding Roll needs to skew. Monday, October 7th, 2019. Minerals argues that skewing is a vital feature for modern High Pressure Grinding Rolls, reducing wear and ensuring optimal grinding across the whole feed, saving energy downstream.
High pressure grinding rolls, also called roller presses, have been used in the treatment of iron ore, copper (Fig.), gold, diamond and various other ore types for many years. 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.
