large size of air jet mill

working principle:   After being frozen, filtered, and dried, compressed air forms a supersonic airflow through the nozzle and is injected into the crushing chamber, causing the material to become fluidized. The accelerated material converges at the intersection of the jet airflow of several nozzles, producing intense collisions, friction, and shearing to achieve ultrafine particle crushing. The crushed material is transported by an upward airflow to the impeller classification area. Under the centrifugal force of the classification wheel and the suction force of the fan, the separation of coarse and fine powder is achieved. The coarse powder returns to the crushing room according to its own gravity for further crushing. Qualified fine powder enters the cyclone collector with the airflow, and the fine dust is collected by the bag filter. The purified gas is discharged by the induced draft fan.   characteristic:   1. Low energy consumption, compared to traditional fluidiz…
