Using Micronization to Reduce API Particle Size

Jan 16, 2013The desired particle size depends on the solid-dosage requirements, notes Brian List, sales and marketing manager at the Jet Pulverizer Company, with typical API particle sizes in the 2–5 micrometer range. The minimum particle size that can be obtained using a jet mill depends on the inner friability of the material, explains List.

Variables in Ball Mill Operation

Of course there is the possibility of over milling, obtaining a different particle size distribution or a need to change media size or mill speed. A general rule of thumb for mill scale-up is √(𝑑/𝐷), where d is the size of the smaller mill and D the inside diameter of the larger mill.
