Stainless steel grading wheel working principle: Materials are moved to the grading area with the ascending airflow under the force of the fan, and are separated into coarse and fine particles under the strong centrifugal force generated by the high-speed rotating grading turbine. 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 fall to the crushing area 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 strong centrifugal force within the grading machine.

The gas-powder mixture entering the classifier first goes into the classifier wheel, where it is subjected to centrifugal force. Larger or heavier particles experience greater centrifugal force and are thus ejected to the outer edge of the classifier wheel and the side wall, no longer influenced by the centrifugal force, and naturally fall 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 classifier wheel and are carried to a higher position by the induced draft fan's force, then smoothly move along the pipeline to the next component for classification or collection. By varying the speed of the classifier wheel using frequency conversion, the magnitude of the centrifugal force in the classifier can be adjusted, achieving the goal of separating particles to the desired size.
