The charge motion in a tumbling mill has been mostly described by empirical, mechanistic and computational models. The computational model presented in this work is a three phase approach for the tumbling mill that combines a particle description for the solids modelled by the Discrete Element Method, and the continuum description for the fluid by CFD approach.

A lab-scale thickener management system was used to perform the flocculation-thickening experiment. This system mainly consists of a deep-cone gravity thickener of 3 litres, a feed tank, a static mixer, three peristaltic pumps (used to transport the feed stream, flocculant solution, and underflow), a stirrer (Dragonlab OS20-S, China), and a motor controller.

flow of particulate solids within these mills can be modelled using the Discrete Element Method (DEM). Typically, such modelling is done for short durations of a few mill revolutions and either in two dimensions or using thin three dimensional slices through the center of the mill with periodic boundary conditions in the axial direction.

power models found in the literature followed by a general description of DEM and CFD stirred mill models as well as the insights that can be drawn from them. Finally, a generic stirred mill power model will be presented and applied to different stirred mill types in order to develop some insights into the differences between different mill types.

CFD modeling of the mill-duct gas and coal flows is compared with experimental data obtained with manual methods in this particular plant. This paper is organized as follows. The geometry, the methodology used to obtain the experimental data and the operating conditions of the furnace are described in Section 2.
