Jet Mills

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.

Jet Mill F.A.Q.

How does jet milling compare with other methods of grinding such as ball mill or a hammer mill? Well-designed, high-speed mechanical mills can grind some friable materials into the low micron size range but wear and product contamination is a serious problem as is attritional heat.

Preliminary Experimental Analysis of a Spiral Jet Mill

Jet mills are common devices used in industry for the fine milling of dry particulate materials. The size reduction is caused by repeated impaction events between particles. Although many parameters affect the performance of a jet-mill, only a few of them have been investigated by researchers to date. Furthermore, the published investigations test only a few materials.
