ConwayBaker et al. [18] studied the effect of the impeller design on the media motion inside a vertical stirred mill by using Positron Emission Particle Tracking (PEPT).Three impellers were tested: a flat blade, a pin type and down pitched impeller. This work highlighted how the impeller strongly influences the upper and lower recirculation loops inside the mill, and consequently, the packing ...

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear. Three different mill ...

stirred mills will vary from sitetosite and from milltomill. Optimization of a given stirred mill with respect to specific energy input depends on the complex relationships between a large set of parameters. Examples include mill speed, media size, media loading, slurry density, slurry flow rate, slurry rheology, feed material characteristics.

For example, the stirrer tip speed of the screwtype vertical stirred mill is approximately 3 m/s [19], whereas it is greater than 15 m/s for the IsaMill [20]. The population balance model (PBM) is a mathematical method that has been used extensively and successfully to describe the breakage behavior of particles in tumbling mills.

Using the shear based power model, Radziszewski (2013) postulated that the power draw of a vertical stirred media mill, operating with pin or disc type stirrers, might be increased by adding stationary liners to the mill shell. If the hypothesis holds true, this approach might be used to improve the design of stirred media mills for new ...
