Jet Mill Micronizer, Fine Milling Equipment by Sturtevant

The Sturtevant Micronizer® is a jet mill (fluid energy mill) employing compressed air or gas to produce particles less than one micron. Inside the Micronizer, precisely aligned jets create a vortex. Material is fed into this vortex along an engineered tangent circle and accelerates.
High-speed rotation subjects the material to particle-on-particle impact, creating increasingly smaller fines. While centrifugal force drives large particles toward the perimeter, fine particles move toward the center where they exit through the vortex finder.
