High-Pressure Grinding - Maschinenfabrik Köppern

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.

The evolution of HPGR technology -

high pressure is applied to the bed of material in a highly controlled manner. This consistent high pressure sets the stage for more efficient size reduction downstream, by creating microcracks in the ore. Tiny microcracks weaken the particles, so that – even if the ore is not shattered – subsequent fine grinding requires the use of less energy

HPGR High Pressure Grinding Rolls

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 70%, while power consumption can be …

High Pressure Grinding Roll HPGR -

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 …

High pressure grinding rolls (HPGR) -

Hydraulic cylinders apply very high pressure to the system, causing inter-particle comminution as the feed travels between the two tires. HRC™ - Mining Magazine award winner 2015! Mining Magazine has recognized 's HRC™3000 high-pressure grinding roll with its annual Minerals Processing award.

POLYCOM high-pressure grinding roll

The grinding elements are two counter-rotating rolls, between which the material is crushed. One roll is designed as a fixed roll and the other one as a floating roll. The required comminution pressure is transmitted via the floating roll. The high-pressure interparticle comminu-tion produces compacted cakes of material
