Airflow crusher

The jet mill, along with a cyclone separator, dust collector, and induced draft fan, forms a complete grinding system. Compressed air, after being filtered and dried, is injected at high speed into the grinding chamber through a Laval nozzle. At the intersection point of multiple high-pressure air streams, the material is repeatedly impacted, rubbed, and sheared, resulting in pulverization. The pulverized material, driven by the fan's suction force, moves with the rising airflow to the classification zone. Under the strong centrifugal force generated by the high-speed rotating classification turbine, coarse and fine materials are separated. Fine particles meeting the required particle size pass through the classification wheel and are collected in the cyclone separator and dust collector, while coarse particles fall back to the grinding zone for further grinding.
