Spiral jet mill for superfine powder production
Achieve consistent ultra-fine powder with precise particle size control, crucial for high-quality pharmaceutical and fine chemical products, ensuring optimal performance and purity.
Achieves Ultrafine Grinding and Particle Classification
The Aeroplex AS Spiral Jet Mill from Hosokawa Alpine stands out for its non-rotating component design, eliminating contamination risks from bearings and lubricants, making it ideal for pharmaceuticals and fine chemicals. This mill utilizes a tangential air injection system through Laval nozzles, creating a spiral jet for efficient particle size reduction. Commonly applied in the production of APIs and fine chemical powders, it features a grinding chamber that supports ultrafine grinding of materials up to a Mohs’ hardness of 3. With its stainless steel construction and optional CIP/SIP capabilities, the Aeroplex AS ensures compliance with GMP standards, allowing easy cleaning and maintenance. The modular design permits easy customization and integration into existing production lines, ensuring seamless automation and process efficiency.
