MQL Fluidized Bed Jet Mill

Single Rotor / Multiple Rotor

widely used in chemical, mineral, metallurgy, abrasives, ceramics, refractory materials, medicines, pesticides, food, health products, new materials and other industries.

  • Available particle size D50:2-45μm.
  • Good particle shape, narrow particle size distribution.
  • Vertically classifier rotor with maximum line speed of 70m/s.
  • Speed of wheel is controlled by converter, particle size can be adjusted freely.
  • Good repeatability of particle size distribution, stable and reliable.
  • Powder product is stable and reliable.
  • The jet mill is 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 line speeds up to 80m/s, ensuring high precision for product requirements
  • Vertical single rotor structure, large production capacity, high efficiency and low investment.
  • High energy utilization rate, promote material flow, improve powder screening efficiency.
  • The pulverization process is completed by the collision of the materials themselves,completely self-grinding,So the device is durable and the purity of products 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 zero contact with metal throughout the pulverization process to meet the requirements of high purity materials
  • The classifying wheel separates the material automatically with airflow, no coarse particles.
  • Grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
  • PLC control system, easy operation.
  • Can be used in series with multi-stage classifiers to produce products with multiple sizes at one time.
  • 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

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.
