Stainless Steel Grading Wheel Working Principle: Materials are moved upwards with the air flow generated by the fan's suction power into the grading zone. Under the strong centrifugal force produced 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 into the cyclone separator and dust collector for collection, while coarse particles descend to the crushing zone for further crushing.

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

The gas-powder mixture entering the grading machine first goes into the grading wheel interior. Under the action of centrifugal force, larger or heavier particles experience greater centrifugal force and are ejected to the outer edge of the grading wheel and the machine's side wall, where they no longer feel the centrifugal force and fall naturally into the crushing main unit for further crushing or drop to the discharge port for collection. Smaller or lighter materials, experiencing less centrifugal force, hover within the grading wheel and are carried to a higher position by the induced draft fan's force, then smoothly move through the pipeline to the next component for grading or collection. By adjusting the grading wheel's speed with a variable frequency controller, the size of the centrifugal force in the grading machine can be modified to achieve the separation of materials into the desired particle sizes.
