fluid energy mills

A novel process for simultaneous milling and coating of …

A fluid energy mill (FEM), instead of commonly used fluidized beds, is utilized to fluidize particulates. Premixed coarse particulates and coating materials are carried into the milling chamber by a high-speed air stream called feeding air. Once inside the chamber, the particulates are diverted and accelerated by so called grinding air …

The Grinding Mechanism in a Fluid Energy Mill and its …

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.
