Principle of fluid energy mill. It is based on the effect and attrition idea. The inlet and exits are connected by a classifier, which stops particles from passing until they are fine enough, as shown in Fig. (a). It aids in the size and shapes determination of particles. The efficiency of air/inert gas is directly proportional to its speed.
