High Pressure Grinding Rolls (HPGR) TAKRAF GmbH

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. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by

HPGR High Pressure Grinding 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.

How HPGRs compare to conventional milling

Aug 19, 2019 Within comminution circuits, High Pressure Grinding Rolls (HPGR) are increasingly replacing conventional SAG, rod and ball mills for hard rock reduction owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional reduction methods, but their wearable

Why HPGRs are revolutionising mill circuits

Aug 07, 2019 High Pressure Grinding Rolls are generally thought to only be effective in controlled “dry” grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR’s the flexibility to fit into a wide array of applications with both wet and dry classification.

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.
