With their excellent throughput capacity, low maintenance requirements and energy efficiency, HPGRs are fast becoming the go-to technology for greenfield projects. 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 ...
(HPGR) as an alternative technology to the conventional semi-autogenous grinding (SAG) milling process for the Morrison Project. The processing plant is designed to operate at 30,000 t/d capacity with an availability of 92%. Results of the trade-off study indicate that the application of HPGR's to the Morrison project
With HPGR technology, the feed material is exposed to very high pressure for a short amount of time. The compressive nature of the HPGR mechanics causes the rock to typically crack and cleave along the grain boundaries, weakening the rock structure and exposing the ore particles.
HPGR technology is considered as a prerequisite step for cement, diamond industry and is now making inroads in copper, gold and iron ores also. The use of HPGR depends mainly upon the cost considerations, downstream benefits and safe practice. However, the HPGR performance is predominantly dependent on its precise working practice which is indeed quite complex. This …

The patent has long since expired and other manufacturers have had a go with the technology; but Polysius remains streets ahead of any copycat supplier and continue to dominate the market. Of the 20 HPGR units currently being used in Australian mines, Polysius has supplied 14 and remains the global leader in this segment.
HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming ever more popular in minerals processing. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls.
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, …

standard practice for decades. HPGR is known to be energy-efficient; the question is how energy efficient? How can the energy efficiency of HPGR be enhanced? This paper reviews recent HPGR applications for the processing particularly of copper, gold, platinum, PGM-Ni-Cu and iron ores. HPGR technology is discussed with respect to energy efficiency.
The application of HPGR technology in comminution circuits is well established for the processing of cement, diamonds and iron ore (Broeckmann & Gardula, 2005), and over the past 10 to 15 years, this technology has slowly been applied to hard ores in hightonnage - precious and base metal operations.
