Vortex-type Fluid Energy Mills (FEM), also called spiral jet mills, are widely employed to grind a variety of materials to low- or sub-micron ranges. In 1936, the design of FEM was first patented by Norwood H. Andrews in the United States [1]. FEM generally have a pretty simple structure and involve no moving parts.

A jet mill, or fluid energy mill, grinds material by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.

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.
The fluid bed jet mills are also different from the loop and pancake mills in that they have grinding nozzles that are directly opposed rather than tangential to the mill body. The direction of the air nozzles produces additional advantages outlined in the case studies of the Fluid Energy Roto-Jet mills described below. Graphite Grinding System
