A jet mill is a type of pulverizer that uses high-velocity compressed air or an inert gas to grind materials into extremely fine powders. Unlike traditional mills that rely on mechanical grinding media like steel balls or hammers, a jet mill accelerates the material’s own particles within a chamber. The intense speed causes the particles to collide with each other, resulting in effective and uniform size reduction through these high-impact collisions.
The key advantage of this method is its ability to produce exceptionally fine, or “micronized,” particles without the risk of contamination from grinding media. This makes jet milling the ideal process for heat-sensitive, abrasive, or high-purity materials where product purity and a sub-micron particle size are critical. The technology is widely used in the pharmaceutical, cosmetics, pigment, and advanced ceramics industries.
