• In spite of the increase in computing power, modeling ball mills is still better described considering only the grinding charge and not the powder in the DEM simulations, relaying on postprocessing the data using a proper population balance formulation to predict grinding.

Abstract. Modelling the pulp fluid and its interaction with both the charge and the mill structure is an interesting challenge. The interaction is normally modelled with a combination of CFD and DEM, where the DEM particles (grinding balls) create the structure through which the fluid penetrates, and in its turn creates forces on the grinding balls.
Wet fine grinding is an important unit process in various industries. In the present work two different stirred media mills (one with a cylindrical stirrer; one with a disc stirrer) and a planetary ball mill are investigated using coupled CFD (computational fluid dynamics) and .
2014). However, the horizontal planetary ball mill is different than the tumbling ball mill in many aspects. Djordjevic (2005) studied the influence of ball charge size distribution on the netpower draw of tumbling mill based on DEM modeling. Charge of the mill was composed from the spherical balls

Advances in Discrete Element Method Application to Grinding Mills 119 to 2D nonspherical to 3D slice to 3D full (Cleary et al. 2003) the prediction of shoulder angle, toe angle, power and vortex center increasingly improved. Obviously, these findings point in the direction of 3D DEM for full scale charge motion plus breakage studies.
CFD Modelling in the Cement Industry Introduction to CFD Engineers are increasing the use of CFD simulation in the design process to validate and optimise designs. The growth in CFD usage is a result of the increasing processing power of computers and improved CFD simulation software. CFD is a branch of fluid dynamics that uses numerical methods to
