The macro-sized particle formation can be done using different mills such as ball mills, hammer mills, colloid mills, fluid energy mills, and roller compression mills. But, for nanoparticles, it is best suited using ball mills based on energy requirements which are further classified as mentioned in Table 12.2 (Sherif El-Eskandarany et al., 2021).Web

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 lab-size versions (as low as to 1 gram/h) up to industrial versions (up to 6 ...Web

Jet mills use no moving parts to apply force, generate no heat, and process material in a single pass. Jet mills use high-pressure (approximately 50-120 psig), turbulent condensed air (or other gases) to force high-velocity collisions between mill feed particles in a one-step milling process, inside a chamber. The mill's power can be adjusted toWeb
