A spiral jet mill is a piece of equipment used to reduce the particle size of pharmaceutical and fine chemical powders down to few micrometers. It is made of different components, each designed for a specific part of the micronization process. The product is first poured in a feeder where it is fed into the product line of […]
FPS has recently cooperated with pharmaceutical industry experts to research best jet mill practices for pharmaceutical. FPS strongly believes in knowledge sharing and continuous improvement. For this reason, FPS President, Eng. Gianola, and Vice President, Mr Corsini, both experts in milling and micronization technologies, worked with M. Nakach Ph.D on a research published in the Pharmaceutical Development and Technology Magazine. Mr. Nakach works at Sanofi. He […]
Issues: Particle size reduction down to low micron is needed Operators must be protected because product is very dusty Large campaigns with expensive product: highest productivity is needed High Potent apis will be added in the future “High Potent Ready” solution: Air-tight separation cyclone with WIP to contain dust Modular micronization equipment for easy integration […]
Contrary to a traditional mechanical mill, a jet mill uses a high-pressure process gas (usually compressed air or nitrogen) as milling energy. Particle-to-particle collision is what reduces the powder size. No mechanical crushing is involved. The most important part of a Jet Mill is the grinding chamber. If is fitted with a series of calibrated nozzles that distributes […]
