MQPW Spiral jet mill

Compressed gas is used to pass the feeder ejector to bring the ground raw materials into the grinding chamber, and driven by the high-speed airflow from multiple nozzles, it is sprayed on the grinding wall in a tangential manner to achieve the effect of friction grinding. By adjusting the longitudinal depth of the grinding chamber, adjusting the grinding pressure or feeding speed, the fineness of grinding can be controlled. Compared with the fluidized bed jet mill, the controllability of the pulverization fineness is less.

• Performance characteristics

  • 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.
