12%The earliest industrial application of high pressure grinding rolls (HPGR) at comminution was in 1984 in the cement industry. Since then, the equipment has been widely applied in mining activities. Despite the rapid spread across the industry, several challenges are still present in the equipment's application, especially considering the complex ore breakage behaviour …

In the present study, a novel approach for modelling the physical interactions between slurry, grinding media and mill structure in a stirred media mill is presented. The slurry is modelled with the particle finite element method (PFEM). The grinding media is modelled using the discrete element method (DEM) and the mill structure

• Fast and simple monitoring, optimizing and control of grinding and crushing circuits. The d80 was calculated in Fig. 9 by changing "n4" and "b4" for flotation feed. The rate of grinding in ball mill No. 2 was n4=0-300 and limitation of "b" was b4=0-2. In "liberation degree" studies, it was resulted that d80 should be 74 microns.

Modeling of wet stirred media mill processes is challenging since it requires the simultaneous modeling of the complex multiphysics in the interactions between grinding media, the moving internal agitator elements, and the grinding fluid. In the present study, a multiphysics model of an HIG5 pilot vertical stirred media mill with a nominal power of 7.5 kW is developed.
