Principle of Stainless Steel Grading Wheel Operation: Under the suction force of the blower, materials move with the rising air stream to the grading area. The coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating grading turbine. Fine particles meeting 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 freely) 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 interior. Under the force of centrifugal force, larger or heavier particles are subjected to greater centrifugal force and are thus thrown to the outer edge of the classifier wheel and the side wall of the classifier, where they are no longer affected by 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 through the pipeline to the next component for classification or collection. By adjusting the speed of the classifier wheel through frequency conversion, the size of the centrifugal force in the classifier can be controlled, achieving the goal of separating particles to the desired size.
