The grinding compressed air enters into the grinding chamber and passes through a certain number of grinding nozzles with a specific angle to produce a high-speed spiral air flow. The material is accelerated into the grinding chamber through the nozzle. Driven by the spiral airflow, the material rotates repeatedly in the grinding chamber at high speed. Because of the different speed, the particles collide with each other, resulting in the crushing effect. Due to the movement of the spiral, the grading effect is produced, and the particles small to a certain extent can be discharged with the air flow and enter the collection device (such as cyclone separator or filter). Coarse particles continue to move in the grinding chamber until they reach a certain fineness.

The Spiral Jet Mill uses compressed gas to bring the raw materials into the pulverizing chamber through the feeding ejector, and under the drive of the high-speed air flow from multiple nozzles, the raw materials are sprayed on the pulverizing wall in a tangent way, so as to achieve the effect of friction pulverization. The grinding fineness can be controlled by adjusting the longitudinal depth of the grinding chamber, the grinding pressure or the feeding speed. Compared with the fluidized bed air pulverizer, the controllability of grinding fineness is poor.
