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 compressive strength with equal …
High pressure grinding rolls (HPGR) - liming
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller stone size.

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, …
Crushing Vs Grinding - MINERALLURGy
Wears are most important in grinding compared to crushing. Because as far we go to finer sizes wears increase due to more collosion requirment for further size reduction. Besides, the grinding media generates extra wears production. The demand for high pressure grinding rolls (HPGRs) increases recently, as they respond to features requirements.

Description DHM Series High Pressure Grinding Roll is a newly crushing and grinding equipment with wide adaptability for fine and superfine material process.
First choice for HPGR technology and service
High pressure grinding is achieved by an advanced type of grinding roll. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls. This particle bed is created between two choke-fed, counter-rotating rolls.
