Ultra-fine powder grinding with jet mills
In industrial applications requiring ultra-fine particle sizes, achieving precise and contamination-free grinding can be crucial. Traditional mechanical mills may not meet the requirements for purity and fine-grade powders, particularly for applications in pharmaceuticals and fine chemicals.
Achieve ultra-fine particle sizes without contamination.
Jet mills from Hosokawa Alpine offer a specialized grinding solution that uses high-velocity gas streams instead of mechanical grinding tools. These mills function by accelerating particles within the grinding chamber, causing them to collide and fragment into finer particles. Notable models include the Aeroplex AS for pharmaceutical applications and various fluidized bed opposed jet mills like the TDG, TFG, and AFG, each tailored for different industrial needs. The TDG model, for instance, incorporates a double-classifying wheel and Vorced Fortex Technology to achieve ultra-fine fineness down to d97 = 1 μm. These mills are suitable for extremely hard or heat-sensitive materials, providing contamination-free grinding with a high degree of efficiency and easy maintenance.
