Estimating energy in grinding using DEM modelling .

In this study several aspects of a SAG mill were investigated using DEM. A pilot scale SAG mill operating at 75% critical speed and drawing 9.94 kW of power is used as the "BaseCase" for the DEM simulation campaign. This BaseCase mill has an internal diameter of 1696 mm, length of 575 mm and has 11 lifters with 50 × 50 mm cross-section.
