HPGR—revolution in Platinum? Metallurgist Mineral Processing Engineer
The HPGR consists of a pair of horizontallyopposed counterrotating rolls, one fixed and the other floating. Feed is introduced to the gap in between the rolls and is crushed by the mechanism of interparticle breakage. The grinding force applied to the crushing zone is controlled by a hydro pneumatic spring on the floating (movable) roll.

Flexible operating parameters Safety ease of maintenance Reduced operating costs less downtime Higher availability reliability
Modelling of HPGR Edge recycling with progressive grinding data
HPGR, has worked for almost 120 years on roller presses, starting with the formation of coal briquettes between two rollers. Subsequently, other fields of application, for fertilizer compaction, emerged. The first HPGR grinding solutions were used in the cement industry where the advantage of energy savings was very welcome on this medium ...
HPGR High Pressure Grinding Rolls Mineral Processing Metallurgy
When is HPGR better than Ball Mill HPGR is typically used in a thirdstage or fourthstage crushing application ahead of grinding. You could always try to build a circuit doing 45 µm classification, but I suspect your circulating load would be overwhelming. Most HPGR applications in hard rock mining achieve 3000 µm to 7000 µm product
A Closer Look at Increasing HPGR Efficiency via Reductions in Edge Effect
Comparison of HPGR Tire Designs Edge effect in traditional HPGR design 3 Edge Effect is the impaired comminution performance at the edges of the HPGR tires due to a reduction in crushing pressure. This results in: • Coarser product size • Uneven wear on the tire surface • Decreased energy efficiency C r u s h i n g P r e s s u r e Tire Width
Minerals Metallurgical Processing
To address this, ''s HRC™ HPGR incorporates an Archframe to maintain a parallel relationship between the rolls and allow for the use of a flanged roll design. We conducted a series of pilotplant tests with a 750 mm by 400 mm HRC HPGR to compare the performance of the flanged roll design against that of a traditional cheek plate ...
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 ...
HRC™e high pressure grinding rolls (HPGR) Outotec
The HRC™e HPGR takes proven technology and enhances it. The high throughput comes from the elimination of the edge effect with the flange design, which will ultimately maximize the amount of crushed material. With the skew control system you will find faster restarts and minimize downtime from skewing events. The HRC ™ e also comes with a ...
