Unique Advantages

Vertical impeller

Vertical classifying turbine design, low rotation speed, wear resistance, low energy consumption;lining with alumina, no metal pollution, meets the requirements of high purity product.

SKF Bearing

SKF bearing makes the transmission run more smoothly and stable.

High precision assembly

High precision assembly, the use of special shaft sleeve, labor-saving, reliable.

High energy efficiency

Air screen type secondary air design, high energy utilization, help material flow, improve the efficiency of powder separation.

Working Principle & Equipment Characteristics

Jet Mill, cyclone, bag filter and fan constitute a complete milling system. After the compressed air is filtered and dried, it is sprayed into the milling cavity at high speed through Laval nozzles. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be milled. The milled materials rise with the suction of the fan. The air flow moves to the classification area, the coarse and fine powder are separated under strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles that meet the particle size requirements are through classifier wheel and collected by cyclone and bag filter; the coarse powder drop to the milling area and continue to be milled.


Vertical & Single Rotor

Fluidized Bed Jet Mill

  • Single rotor classifier, rotor diameter from 150mm to 2200mm, rotor speed 340 ~ 10000rpm;
  • The range of particle size is 2 ~ 45μm;
  • The materials are directly fed into the classifying area from the bottom of the classifier by the classifying airflow;
  • With thermal sensor and speed sensor, suitable for inverter operation;
  • Easy to use wear-resistant lining, used for classification of abrasive materials.

Vertical & Multi-rotor

Fluidized Bed Jet Mill
