Jet Mill Grinds to Nano-Particle Size

The Micronizer is a fluid energy mill employing compressed air, steam, or gas to produce particles less than one micron. The Micronizer advantage is its simple design that allows for quick and easy cleaning and material changeover. It is used in a wide variety of applications where very small particle size, increased surface area, and narrow particle size distribution are critical. Typical applications include TiO2, cosmetics, pigments, pharmaceutical powders, carbon black, agricultural chemicals, precious metals, resins, heat-sensitive materials, and high-performance materials. 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.
