Working Principle of Horizontal Fluidized Bed Jet Mill
MQW jet mill is a Fluidised Bed Opposed Jet Mill, with built-in horizontal classifying wheels (single wheel or multiple wheels). After the compressed air is filtered and dried, it is sprayed into the grinding chamber through the Laval nozzle at high speed. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The ground materials rise with the suction force of the fan. The airflow moves to the classifying area, under the strong centrifugal force generated by the high-speed rotating classifying turbine, the coarse and fine materials are separated, the fine particles that meet the particle size requirements enter the cyclone separator and dust collector through the classifying wheel, and the coarse particles descend to the grinding area to continue grinding.
Technical Advantages of Horizontal Fluidized Bed Jet Mill
- Designed to allow quick and easy cleaning
- Integrated ultra-fine classifier for extremely spatter grain free end products with a steep particle size
- Classifying wheel with vertically mounted drive can be opened hydraulically 180° for cleaning
- Loss in weight control system with load cells
- Low noise emissions <83-85 dB(A)
- Standard design is pressure shock proof to 10 bar overpressure
