Fluidized Bed Jet Mill
🔹 Zero Contamination
🔹 10–3000 kg/h
🔹 ISO 9001
🔹 CE Available
Product Overview
The MQW Series Fluidized Bed Jet Mill uses high-pressure compressed air to accelerate particles into a grinding chamber where they collide at high velocity. The fluidized bed design ensures uniform particle distribution and efficient classification, producing ultra-fine powders with narrow particle size distribution.
Unlike mechanical mills, our jet mill operates at low temperatures — making it perfect for heat-sensitive materials such as pharmaceuticals, chemicals, and food ingredients. The ceramic or stainless steel lining eliminates metal contamination, meeting the strictest purity standards.
Key Advantages
- Ultra-Fine Grinding: Achieves d97: 3–45 μm with precise particle size control
- Zero Metal Contamination: Ceramic (Al₂O₃ / ZrO₂) or SS316L lining options
- Low Temperature Operation: No heat generation, ideal for heat-sensitive materials
- High Purity: Compressed air medium, no grinding media contamination
- Narrow Particle Distribution: Integrated air classifier ensures uniform output
- Easy Maintenance: Modular design with quick-access panels
- Automated Control: PLC system with touchscreen interface
- Energy Efficient: Optimized nozzle design reduces air consumption
Working Principle
Compressed air is accelerated through specially designed supersonic nozzels into the grinding chamber. Material is fed via a screw feeder into the fluidized bed where particles collide at high speed. The centrifugal force created by the classifier wheel separates fine particles from coarse ones — coarse particles return to the bed for further grinding while qualified fine powder exits through the classifier into the collection system.
