The aim was to produce fine silica particles with a high sphericity and smooth surface so as to reduce abrasivity. Tests in a fluidized bed opposed jet mill showed that the circularity of the ground particles depended on the classifier speed and that a speed of 10 000 rpm gave particles with narrow size distribution and high circularity.

Due to the uneven materials dispersion and high dust concentration in industrial applications of turbo air classifiers, a highefficiency rotor classifier was designed. Numerical simulations by ANSYSFluent, the effects of rotor cage shape, the number of blades, and the blade profile on the inner flow field, as well as classification performance, were investigated. The simulation results ...

Indeed, according to Boulvin et al. [44], experimental data from a grinding circuit show that mill throughput impacts the separating curve. A recent experimental study on parameters affecting the VRM performance shows a correlation between product fineness and dynamic separator speed, mill throughput, and the rollers hydraulic pressure applied to the grinding table of the VRM [45].
