Air jet milling, or more correctly fluid energy milling, uses high velocity jets of gas to impart energy to particles for size reduction. Air jet mills have mainly been developed for producing fine particles of below 50 mm. Most models are available in many sizes from labsize versions (as low as to 1 gram/h) up to industrial versions (up to 6 ...
