MQL Fluidized Bed Jet Mill

General introduction to MQL Fluidized Bed Jet Mill

　　On the basis of traditional fluidized bed pulverizer design, combined with our company's self split classification technology, its performance is far better than domestic fluidized bed air flow pulverizer. After being frozen, filtered and dried, the compressed air is injected into the crushing chamber through the nozzle to form a supersonic air flow, which makes the material fluidized. The accelerated material converges at the intersection of the jet air flow of several nozzles, resulting in severe collision, friction and shearing, so as to achieve the ultra-fine crushing of particles.

Advantages of MQL Fluidized Bed Jet Mill

　　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 of MQL 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.
