Spiral jet mill for superfine powder production
In pharmaceutical and fine chemical manufacturing, achieving ultra-fine particle sizes without contamination is crucial. Traditional milling methods often struggle with cleanliness and particle size control, impacting the quality and purity of the final product.
Produces ultra-fine particles with no contamination risk
The Aeroplex AS by Hosokawa Alpine is a spiral jet mill designed for superfine comminution of soft materials up to a Mohs’ hardness of 3. Its flat-cylindrical grinding chamber and absence of rotating components eliminate the need for lubricants, thereby avoiding contamination. The mill uses high-pressure air injected via Laval nozzles to create a spiral air jet for particle collision and size reduction. The system supports easy cleaning and sterilization, ideal for pharmaceutical applications demanding high purity. Capable of producing particle sizes in the range of 10 to 150 µm, the mill offers consistent performance for materials with brittle-crystalline fracture behavior. The compact design ensures ease of handling and maintenance, and the adjustable nozzle angles allow precise control over particle fineness.
