Jet Mills | Glen Mills, Inc.
A jet mill grinds materials 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.

Analysis of the particle collision behavior in spiral jet milling
A spiral jet mill is categorized as a dry-type media-less grinding machine. Generally, it has the following three advantages compared with dry-type mechanical mills [1]: (1) Particle size distributions (PSDs) are narrow due to the classification effect. (2) Contamination amount is less because of autogenous grinding.
