The last major development has been high pressure grinding rolls ("HPGR"), first used in 1985 in a cement plant. HPGR are used as a form of tertiary crushing, often replacing semi-autogenous grinding ("SAG") mills. They are much more energy efficient, produce a higher proportion of fines, and leave the coarser fragments fractured and ...

At the same time, the uniform pressure profile in the milling gap results in better grinding and more even roller wear. This prolongs the service life of the rolls by up to 30%. Through reducing the so-called bathtub effect the rolls need to be replaced less frequently – and your HPGR Pro will run longer with fewer downtimes.
With the advent of high-pressure grinding rolls (HPGR) in the 1980's, the comminution process efficiency improved to some extent in terms of energy savings. In HPGR, particle breakage is the result of high inter-particle stresses generated when a bed of solids is compressed moving through the narrow gap created between two pressurized rolls.

These abrasive rolls work with Performax, Jet, Super Max and many other drums sanders that require 3" wide rolls or wraps. The pr-cut rolls are cut to match your machine drum size. The rolls are made of an industrial grade aluminum oxide abrasive to give long life and produce a high quality finish.
The second type is known as 'high pressure grinding roll' (HPGR), in which each of the minerals or rocks are reduced in size by using compressive and interparticle pressure which is mathematically configured beforehand. Like the cone crusher, some of the most common applications that use roll crushers are ores, aggregates and unprepared rocks.
High pressure grinding rolls (HPGR) - Outotec. 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 ...

garnet high pressure grinding rolls niepoetter-montagen.de. high pressure grinding rolls . However, cements which have been ground in a circuit of high pressure grinding rolls and separator as a rule display a narrower particle size distribution and thus a higher water requirement than a ball-mill cement.
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.
