YDBK Series Jet Mill | Fluidized Bed Jet Mill
- What Is a Jet Mill?
A jet mill, also known as an air jet mill or fluidized bed jet mill, is a high-precision grinding system that uses high-speed compressed air to achieve ultra-fine powder pulverization.
Unlike traditional mechanical impact mills, the jet mill relies on particle-to-particle collision to achieve size reduction, ensuring no metal contamination and maintaining the purity of even the most sensitive materials.
- Principe de fonctionnement
The YDBK Series Jet Mill adopts a fluidized bed structure integrated with a built-in air classification system.
Compressed air or nitrogen is introduced through multiple special nozzles at supersonic speed, forming a high-energy airflow inside the grinding chamber.
The raw material is fluidized by the airflow and continuously collides with other particles, gradually being reduced to micron-level fineness.
The internal classifier wheel automatically separates fine powder from coarser particles — fine powder is discharged through the outlet, while larger particles return to the grinding zone for further milling.
