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, abrasive ores.
When selecting an HRC™ HPGR model, mining operators should consider ore top size, capacity and overall circuit design. The HRC™ HPGR is best suited for crushing in high-tonnage, hard rock applications. Common circuits utilize high pressure grinding rolls in a number of ways: • Tertiary crusher, followed by a ball mill or VERTIMILL®
High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.
High capacity High Pressure Grinding Rolls for all your use cases. During its relatively short history in minerals processing, HPGR technology has undergone significant development in machine roll wear surfaces and control philosophy.
a primary mill in combination with – for example – tube mills, as a component of combi grinding systems, or as an independent finishing mill. The larger the amount of grind-ing work performed by the high-pressure grinding roll, the greater is the energy saving. Modern, user-friendly regu-lating, monitoring and control devices, combined with

Comminution in HPGR is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous (SAG) mills.
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 .
