ABSTRACT:
A method and arrangement for multiple stage micronization of sticky material such as clays, sulphur, and pigments is disclosed. The sticky materials are milled by opposing vortices created by high velocity streams of gas or air. Average velocities of at least 60 m/sec are induced within the individual milling chambers by a rapidly rotating rotor and stator acting in different directions. This produces an even stream within the milling chambers, whereby the material being milled travels on a carrier gas without agglomeration. The material to be milled is crumbled within the first milling chamber and transferred to the periphery of the chamber by the main vortices, were a plurality of microvortices disposed tangentially with respect to the main vortex perform the actual milling process. The milled material enters a second milling chamber, and additional chambers thereafter, through a plurality of centripetal channels disposed along a pressure differential. Further milling occurs in these chambers in the same manner as in the first chamber. This method and arrangement for micronization permits milling in a liquid-gas medium.
