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.

Working Principle. Plastic Granules are fed into Mil system thru Hopper, where it is crushed in between two Disks, thus minced to Powder form which is passed thru screening system to get the desired size of Powder. The screen also serves as a separator to separate Coarser powder for refeeding into Mill via a closedloop system recycle.

The Operating Principal. P ulverization takes place in the central chamber of the MicronMaster® 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 highvelocity collisions between particles of the process material itself.
