The high pressure grinding roll machine comprises a pair of counter-rotating rolls mounted in a sturdy frame. One roll is fixed in the frame, while the other is allowed to float on rails and is positioned using pneumo-hydraulic springs. The feed is introduced to the gap between the rolls and is crushed by the mechanism of interparticle breakage.
to enhance grinding productivity of the HPGR. — High pressure grinding rolls in mineral processing Moving from cement to hard rock High pressure grinding rolls (HPGRs), also known as roller presses, are rapidly gaining acceptance in hard-rock processing, primarily due to their energy efficiency when reducing mineral ore to fragments.
High pressure grinding rolls are a good alternative for comminution. This device presents low operative cost and high energy performance. Modelling of 16 mono-size assays have been carried out using grinding rolls with controlled operative pressure and tangential velocity. Back-calculation of the different
A rolling success For decades, polycom ® high-pressure grinding rolls have been used successfully in the grinding of raw materials and binding agents. polycom ® HPGR grinding is based on the principle of supplying the material to be ground to two counter-rotating rolls
Köppern – Specialists in High-Pressure Comminution 7 Improved Cost-Efficiency High-pressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. The technology has found its key application in the liberation of diamonds and also in primary comminution.
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.
High pressure grinding rolls are preferred for their energy efficiency and flexibility in ore processing. 's unique take on this technology, the HRC™ HPGR, delivers even bigger – as the most advanced high pressure grinding roll on the market.
