General introduction to MQPW Spiral Jet Mill

  Compared with the fluidized bed air flow mill, the disc air flow mill has a good crushing effect on viscous materials, and the crushing process will not produce the phenomenon of blocking material and unable to crush.

Advantages of MQPW Spiral Jet Mill

  Available particle size D50:1.5-25μm.

  Many nozzles are installed for high grinding efficiency.

  Built-in calssifying wheel for high precision.

  Speed of calssifying wheel is controlled by converter, particle size can be adjusted freely.

  Good particle shape, narrow particle size distribution.

  Constant temperature(20°C) or low temperature, medium-free grinding, especially suitable for materials of heat sensitive, low melting point, sugary, volatile nature.

  The grinding process is completed by the collision of the materials themselves., Fully self-grinding, So The device is durable and the purity of products is high in contrast.

  No residual material, achieve explosion-proof design, no safety hazards, cleaning is very simple, easy to disassemble and replace parts.

  Key parts like inner liner, classifying wheel and nozzle are made of ceramic such as aluminum oxide, zirconium oxide or silicon carbide, ensuring non-contact with metal throughout the grinding for high purity of the final product.

  Grinding is in closed system, low dust and noise, clean and environmentally friendly production process.

  PLC control system, easy operation.

  Optional explosion-proof design, can also be upgraded to nitrogen circulation system to meet the ultra-fine grinding processing requirements of flammable and explosive oxide materials.

Working principle of MQPW Spiral Jet Mill

  Jet Mill works with cyclone separator, dust collector and suction fan to form a complete grinding system. Compressed air flow after filtration and drying would go into milling chamber from nozzles, and meet in the center area, where material would be impacted and ground and sheared. Milled powder would go up to the classifying chamber by the air flow from suction fan. The high-speed rotation of classifier wheel would create a strong centrifugal force to separate coarse powder and fine powder. Qualified fine powder would go through the wheel vane then into the cyclone separator or dust collector, while mixture of coarse powder and fine powder would fall down to the milling chamber to be milled again.
