Investigating grinding media dynamics inside a vertical stirred mill
Conway-Baker 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 …

Calculating breakage parameters of a batch vertical stirred mill
The selection function in the vertical stirred mill can be described by a linear function for limestone and depends on the process conditions, but remains parallel in log-log space as the gradient function is constant for a given ore. The test result shows that higher mill tip speed, lower solids concentration and smaller grinding media size ...
