High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
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.
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.
CSP High Pressure Grinding Rolls (HPGR) CSP is a leading worldwide supplier of HPGR Rolls to OEM and aftermarket. We have many successful working applications having supplied hundreds of sets of HPGR Rolls to a variety of worldwide mining and mineral processing operations including Iron Ore, Diamond, Molybdenum, Gold and Copper. ...

Mining and processing for the Pilgangoora lithium-tantalum project. Pilgangoora is a conventional drill, blast, load, and haul open-pit mining operation. ... grinding through high-pressure grinding rolls (HPGR), flotation, magnetic separation, and dewatering for the production of concentrates.
2 The high-pressure grinding roll has proven to be extremely effective for the grinding of mineral raw materials. With numerous POLYCOM® installations in different industrial sectors, ThyssenKrupp Industrial Solutions is the worldwide market leader for this technology.
Why your High Pressure Grinding Roll needs to skew Skewing is a vital feature for High Pressure Grinding Rolls, reducing wear and ensuring optimal grinding across the whole feed, saving energy downstream. Explore the findings of our new white paper.
The process of high-pressure grinding and the properties of its product are very different from those of conventional crushers or grinding mills, and the industry has learned to use this to its advantage in new applications. Today, the iron-ore industry uses HPGRs to prepare pellet feed for finishing grinding after wet-ball milling and filtering.
The main objective of this work is to optimize the grinding technologies for tantalum ores with high pressure grinding rolls. The selected ore for this study was an altered leucogranite from the Penouta Open Pit Mine (NW Spain). In the present work mono-size experiments have been carried out using grinding rolls with controlled pressure.

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.
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
Grinding developed by a combination of high-pressure grinding rolls (HPGR) followed by a ball mill (BM) was compared with a single ball mill process. The mineral characteristics of the grinding products were analyzed using a Tescan Integrated Mineralogical .
