a scale up model for hpgr hard rock grinding

Modeling the contribution of specific grinding pressure

The interest in the evaluation of HPGR technology in hard rock grinding, especially for Vale''s green field projects, requires a suitable model for simulation of this type of mill. This paper discusses some of the elements of the development of a procedure for characterizing HPGR grinding and the implementation of a HPGR model in Modsim™.

High Pressure Grinding Roll for advanced crushing FL

By the late 1990s the HPGR became standard equipment for processing iron ores. Successful hard rock mining installations followed about a decade later and HPGR appliions have been expanding into base and precious metals flowsheets around the globe ever since, as the technology continues to prove itself on more complex and harder ores.
