Minas-Rio is an Anglo American property, located in Brazil, which started its operation at the end of 2014. The Minas-Rio regrind circuit is currently the largest Vertimill™ installation in the world with sixteen Metso VTM-1500s installed in closed circuit with hydrocyclones. The grinding efficiency of this circuit was verified through a sampling campaign, and the results showed that the measured...
This paper shall review Metso Minerals’ current 3D Discrete Element Method (DEM) modeling techniques, developed to allow a detailed study of the interactions of crushing design variables with actual rock mechanics.A standard DEM approach cannot be applied to systems where size reduction is an important element in the flow of particles, such as industrial crushers. In these systems, it is necessary...
