In air-jet milling (fluid energy milling), compressed air having a high velocity is used for particle size reduction. The particle-particle collision leads to fine particles of sizes up to about 5 µm . The advantage of air jet milling is the absence of any moving parts in the grinding chamber. This avoids the contamination of the final product.
