WEBApr 1, 2016 · Citic SMCC's slurry flow model for AG/SAG mills (grate discharge mills) was constructed using the approach originally adopted by Morrell and Stephenson (1996) who related the volume of slurry heldup in the mill to its rate of flow out of the grates. Morrell and Stephenson incorporated the effects of grate design, mill speed and charge volume.
WEBAug 1, 2019 · Soleymani et al. [9] found that the mill power increases with mill speed, but the mill power first increases and then decreases in the increase of slurry filling. Studying the impact of mill speed and slurry filling on the charge dynamics can be helpful to improve the grinding efficiency and the accuracy of numerical simulation.
