Stainless steel grading wheel working principle: Under the force of the blower, materials are moved upwards with the ascending air stream to the grading area. With the strong centrifugal force generated by the high-speed rotating grading turbine, coarse and fine materials are separated. Fine particles that meet the particle size requirements pass through the grading wheel and enter the cyclone separator and dust collector for collection, while coarse particles fall to the crushing area for further crushing.

The motor drives the stainless steel grading wheel to rotate at high speed within the grading housing (speed can be adjusted freely), generating a strong centrifugal force within the grading machine.

The gas-powder mixture entering the grading machine first enters the interior of the grading wheel. Under the action of centrifugal force, larger or heavier particles experience greater centrifugal force and are thus ejected to the outer edge of the grading wheel and the side wall of the machine, where they no longer feel the centrifugal force and naturally fall into the crushing main unit for further crushing or to the discharge outlet for collection. Smaller or lighter materials are subject to less centrifugal force and remain suspended within the grading wheel. They are then carried to a higher position by the induced draft fan's airflow and moved along the pipeline to the next component for grading or collection. The speed of the grading wheel can be adjusted by varying the frequency, thereby controlling the centrifugal force within the grading machine to achieve the desired particle size separation.
