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.
Fluidized Bed Opposed Air Jet Mill: After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction of the fan. The airflow moves to the classification zone. Under the action of the strong centrifugal force generated by the high-speed rotating classification 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 classification wheel for collection, and the coarse particles descend to the crushing zone and continue to be crushed.
