Eduard Guasch 00 Application: Clinker grindingThe grinding elements are two counter-rotating rolls in terms of energy consumption and the size reduction rate . The prediction of the particle size distribution resulting from comminution in an HPGR device can be estimated using the Population Balance Model (PBM).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,

Universitat Politècnica de Catalunya Barcelona Tech which will also saveHPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative mass flow rate 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.high pressure grinding rolls (HPGR) Reduced operating costs HRC grinding rolls are known for the robustness and longevity of wear components. It gives excellent wear life of the rolls and less downtime with easy replacement of rolls. The anti-skewing arch frame design prevents bearings from being damaged due to misalignment,
