The interactions between slurry, grinding media and mill structure are modelled by two-way couplings between the PFEM, the DEM and the FEM models. The coupled model of the present study is used to predict the motion of slurry and grinding media, and to calculate the power draw during wet comminution in a pilot scale …

The effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material. It was found that slurry density determined the distribution of solid charge in the mill, with migration of particles from the tumbling zone to the mill periphery as solid concentration was progressively increased.

In the absence of any dispersant, the typical maximum percentage solids in a slurry is approximately 27.4% by volume for the feed of ultra-fine grinding in stirred media mills, whereas an upper limitation of solids concentration is up to 60.15 vol.% in the presence of an optimal dispersant (Greenwood et al., 2002). Therefore, the …
