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 (HPGR) In Comparison to SAG Milling Technology Presented by: Hassan Ghaffari, P.Eng. Raytcho Anguelov, P.Eng. Jake Alexander, MBA
The latest and most successful new comminution technology has been the high-pressure grinding rolls (HPGR), which have proved to be highly efficient in energy consumption and to have a relatively high throughput rate at low steel consumption. ... With limestone (soft material), the roll surface is coated with a material film which increases the ...
Grinding of mineral mixtures in high-pressure grinding rolls. (soft material) the roll surface is coated with a material film which increases the external friction between the material and the rolls. This effect causes more material to be drawn between the rolls and hence the gap to increase.

1.. IntroductionHigh-pressure roll grinding has achieved considerable popularity over the last several years given its potential of improving capacity and reducing energy consumption in a grinding circuit (Schönert, 1988, Fuerstenau et al., 1995, Norgate and Weller, 1994)minution in the high-pressure grinding roll (HPGR) is the result of the high interparticle stresses generated when a ...
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.
Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to …
