4. Classifier: Some fluid energy mills include a classifier to separate fine particles from coarser ones. The classifier ensures that only particles of the desired size exit the mill. 5. Outlet: Reduced particles exit the mill, and the gas stream, along with finer particles, may recirculate for further size reduction. Working: 1.

Fluid energy mill based on the principle of Impact and Attrition. Size reduction takes place by a high-velocity collision between particles. Construction of Fluid Energy Mill. It consists of a loop of pipe, which has a diameter of 20 to 200 mm. The height of the loop may be up to 2m. Several nozzles are fitted at the bottom of the pipe.

Fluid energy mills are used because of their advantages in fine grinding. The materials fed into a jet stream are accelerated to a relatively high velocity from 10 to 200 m/s and although these values are much higher than those encountered in the breeding process of crystals, there are some similarities between these two operations.
