From the moment we started work on our jet mill, we had an ambitious goal in mind. We wanted to create a device that responds to the most important challenges related to the production of high-quality materials. We were particularly interested in launching a mill that would be perfect for the production of friction materials and grinding processes requiring high purity. The jet mill offered by Comex is characterized by low energy requirements. Thanks to the use of the highest quality components for its production, the mill is characterized by a low degree of wear of parts. The combination of the grinding chamber with the ACX classifier guarantees high precision of the process and significantly contributes to improving its productivity. The mill gives the possibility of changing the shape of the grain composition curve and allows the production of fine grain up to 2 microns (at d97). How does the Comex jet mill work? The principle of jet milling in a dynamic slurry is illustrated in the figure below. It shows a stream of compressed air entering the grinding chamber and accelerating the particles. The initial velocities of the particles are very small. After acceleration, they reach supersonic speed in the axis of the chamber. Optimum optimal conditions occur when the air pressure in the nozzle area is both high enough to entrain enough particles and not too high so that the amount of mass does not inhibit the stream velocity. The highest speed of the maximum number of particles at the point of collision determines the optimal productivity of the mill.
