MQW series multi rotor fluidized bed Jet Mill

After the compressed air is filtered and dried, it is sprayed into the crushing chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure air streams, the materials are repeatedly collided, rubbed and sheared. The crushed materials move to the classification area with the rising air stream under the pumping force of the fan. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, The fine particles meeting the particle size requirements enter the cyclone separator and dust collector through the grading wheel for collection, and the coarse particles drop to the crushing area for further crushing.

• Performance characteristics

  • Available particle size D50:1-25μm.
  • Good particle shape, narrow particle size distribution.
  • Rotation speed of classifier wheel is controlled by inverter, particle size can be adjusted freely.
  • Ultrafine powder product is stable and reliable.
  • Suitable for dry grinding of various materials with Moh’s hardness below 9, especially for the materials with high hardness, high purity and high added value.
  • Constant temperature or low temperature, medium-free grinding, especially suitable for materials of heat sensitive, low melting point, sugary, volatile nature.
  • The world’s leading high-precision classifier rotor with linear speeds up to 80m/s, ensuring high precision for product requirements.
  • High energy utilization rate, promote material flow, improve powder separating efficiency.
  • The grinding process is completed by the collision of the materials themselves., Fully self-grinding, So this device is durable and products purity is high in contrast.
  • 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
  • The classifying wheel separates the material automatically with airflow, no oversize particles.
  • Grinding is in closed system, low dust and noise, clean and environmentally friendly.
  • PLC control system, easy operation.
  • The motor can be connected with belt to increase rotating speed.
  • Can be used in series with multi-stage classifiers to produce products with multiple sizes.
  • Weighing control system, high precision, optional, high product stability.
  • 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.
