Micronization is an established technology and manufacturing technique for producing APIs within a 1–10 micron average particle size. We utilize proprietary jet milling technology to effectively meet specific particle size distribution targets across the full range of compound properties. Phase-appropriate jet mills are in place for non-GMP ...
One of the most important characteristics of a jet milled product is the huge increase in surface area. When reduced to 5 microns, a 30 mesh product has 1,643,000 times more particles and the surface area is 118 times greater. This allows faster reaction times for chemicals, faster burn rates in solid fuel rockets (air to air missiles) more ...
Grinding in a spiral jet mill is achieved as a result of particle collisions caused by high velocity gas exiting a series of nozzles situated around a grind chamber as per Fig. (1) which shows the plan view and process description of a spiral jet mill and Fig. (2) which shows a side view.
