  • Jet milling Hovione

    Jet milling is the standard API particle size reduction method. The powder is fed into a milling chamber where compressed air/nitrogen, usually in a vortex motion, promotes particle-to-particle collisions. Particle classification is made by inertia, following reduction via impaction and abrasion. Applications
