Compressed air is accelerated into supersonic airflow through a nozzle and then injected into the crushing zone, causing the material to become fluidized (the airflow expands to form a fluidized bed that floats and boils, colliding with each other), thus ensuring that each particle has the same state of motion.

In the crushing zone, accelerated particles collide and crush at the intersection of the nozzles. The crushed material is then transported to the grading zone by an upward airflow, where it is sifted through a high-speed rotating grading wheel to separate fine particles meeting the size requirements. Coarse particles that do not meet the size requirements are returned to the crushing zone for further crushing. Qualified fine particles are carried by the airflow into a cyclone collector for collection, and the dust-laden gas is filtered and purified by a dust collector before being released into the atmosphere.
