HPGR High Pressure Grinding Rolls Weir

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 ...

High Pressure Grinding Rolls (HPGR) - TAKRAF GmbH

Feed material can be smaller than the gap, which is an important distinction as compared to crushers, for example. The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the ...

HPGR High Pressure Grinding Rolls

14/07/2016  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 ...

First choice for HPGR technology and service

A High Pressure Grinding Roll produces a particle size distribution (PSD) that is wider, with more fines, than a tertiary crusher (e.g. cone crusher) would produce. The reason is that the compressive force not only acts on the coarse end of the PSD, but throughout the particle bed on both coarse and fine particles, including the fine particles derived from the initially coarser fractions.
