The Enduron HPGR mechanism involves inter-particle grinding, achieved through the action of two counter rotating rolls that compress the feed bed, enabling particles to grind one another.
Communition Equipment - Enduron High Pressure . 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 ...
High pressure grinding roll - saving energy and providing results. The HPGR truly is a unique comminution product. It weakens rock structure and exposes ore particles, making it an attractive option for heap leach applications.
With industry demand for high pressure grinding rolls HPGR on the up, Weir Minerals is arguing that skewing is a vital feature for modern HPGRs to reduce wear, save downstream energy and ensure optimal grinding across the whole feed. The company was sharing its findings following the publication of a new white paper.

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 grain size.
