2015-7-1 Fluid energy milling, sometimes referred to as air jet milling, effectively reduces the size of drug particles from the range of 20–100 μm to less than 10 μm. In this micronization method, high velocity compressed air streams are injected into a chamber where the starting raw materials are fed by a rate-controlled feeder . As the particles enter the air stream, they are accelerated and caused to collide with each other and the wall of the milling
