influence of jet milling parameters

About this site

Apr 25, 2015  The effect of jet milling pressure, and in turn the milling speed, was investigated systematically in this work. The jet milling was carried out at various pressures of 20, 40, 60 and 80 psi keeping the other process parameters unchanged.Fig.␣1 shows the SEM images of the jet milled powders synthesized at various pressures. As evident from Fig.␣1, the particle size is drastically

Mar 01, 2014  Fig. 1 shows the particle size distributions of the powders ground at different classifier frequencies and grinding gas pressures. It is clear that the process parameters of jet mill have a great impact on the particle size distribution of the ground produces. Furthermore, the influence of classifier frequency takes a leading position compared with that of grinding gas pressure.

About this site

Jan 15, 2017  Jet milling is classified as a fluid energy impact-milling technique generally used for producing ultrafine powders. The final particle size produced by this method is very much dependent on the material being processed (Protonotariou, Drakos, Evageliou, Ritzoulis, Mandala, 2014). The jet mill is a static machine with no grinding media.

Jet mill - Wikipedia

A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size while continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. Particles leaving the mill can be separated from the gas stream by cyclonic separation.
