Unlike mechanical milling, many jet mills involve no moving parts any sort and instead relies on air, gas or steam jets to break up the particles. These high-velocity jets are used to drive the material around the grinding chamber, creating collisions between particles of the process material.

Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills, which was only possible by means of wet media milling process at the past. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet ® System uses superheated steam as its milling gas.

If the fine particles generated are a concern, we can use a secondary air classification step to remove those particles. Many of our jet mills have internal classifiers, which allows for a precise cut point on the coarse end. All our jet mills feature a ceramic alumina lining to prevent iron contamination during the jet milling process.

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.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

In the case of hammer or jet mills, such devices are integrated in the mill. Quite often, a reduced fraction of fines can be of advantage for the final application, like in carbon brush and batteries. In this case, special classifiers adapted to the fine particle size range (0-10 µm) have to be used in a separate processing step after milling.

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
