General introduction to MQW Fluidized Bed Jet Mill

  A fluidized bed airflow pulverizer is a kind of pulverizer, in which the compressed air is frozen, filtered, and dried, and then injected into the pulverizing chamber through the nozzle to form supersonic airflow, so that the material is fluidized. The accelerated material is converged at the intersection of the jet airflow of several nozzles, resulting in a violent collision, friction, and shear to achieve the ultra-fine pulverization of particles.

Advantages of MQW Fluidized Bed Jet Mill

  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.

Working principle of MQW Fluidized Bed Jet Mill

  Fluidized bed jet mill works with feeding device, cyclone, bag filter and suction fan to form a complete grinding line. 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, milled and sheared.

  Milled powder would go up to classifying area by airflow. The high-speed rotation of classifier wheel would separate oversize powder and fine powder. Qualified fine powder would go through the wheel impeller and output cyclone or bag filter, while oversize powder would fall to milling area to be milled again.
