Fluidized Bed Jet Mill

Suitable for grinding materials with high hardness, high purity and high added value.

  • Low-temperature pulverization without medium, especially suitable for heat-sensitive, low-melting materials.
  • Control particle sizes precisely, available particle size D50:1~25μm.
  • Grinding in a complete closed system, no dust, low noise, clean and environmentally friendly.

According to different materials and application industries, the production capacity and particle size range will be different.

Working Principle

After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction of the fan. The airflow moves to the classification zone. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator and dust collector through the classification wheel for collection, and the coarse particles descend to the crushing zone and continue to be crushed.
