Milling/micronizing platform that renders product ignition or explosion impossible

Produced by Frewitt Engineering Works

From potent APIs to fuels and many other powder ingredients, numerous products are susceptible to explosion, oxidation, and heat damage because of the kinetic energy required for milling products to the necessary particle sizes. Potent APIs can also endanger employees during handling. Manufacturers are therefore obliged to install containment measures. With the Pin Mill PMV-320, the entire milling process takes place in a vacuum (negative atmosphere), depriving products of sufficient air to ignite, heat, or oxidize. The negative pressure atmosphere enables processes to be contained easily, without costly and complex security measures. Moreover, the process – despite turning at speeds exceeding 200 m/s – is almost silent, which also enables users to forego hearing protection.

With a turn-key solution that does not require large amounts of nitrogen gas to mitigate explosion risk, Frewitt claims that the system will result in increased safety, while also helping preserve the active properties of medications by avoiding heat and oxidation.
