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 compressive strength with equal pressure being applied to

Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984). The first commercial application of HPGR was in 1985 and its success resulted in increasing numbers of applications since then, particularly in the cement industry ( Kellerwessel, 1990 ).

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.

In high-pressure roll milling, the rate at which dry particles can be fed to the mill is limited by the upward flow of air being evolved as the bed of particles is compressed in the gap. For the experiments that were conducted in this work, we found that the throughput dropped as the gap decreased.

The Bepex Roll Compactor is a high-pressure agglomerator, able to press fine and often highly aerated solids into larger, cohesive masses with controlled densities. Agglomeration is performed by compressing fine material between two opposed, counter-rotating rolls held under pressure. By utilizing high pressure to agglomerate, you often eliminate the need for a liquid binder and the ensuing

The technology''s working principle is that two counter-rotating 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.

Primary grinding in the high-pressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode. Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed. Thus, some of the
