Stainless steel grading wheel working principle: Under the action of the fan's suction force, materials move with the rising air current to the grading area. Due to 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 into the cyclone separator and dust collector for collection, while coarse particles descend 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 ejected to the outer edge of the classifier wheel and the side wall of the classifier, 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 experience less centrifugal force, remain suspended in the classifier wheel interior, and are carried to a higher position by the induced draft fan's force, then flow along the pipeline to the next component for classification or collection. By adjusting the speed of the classifier wheel through variable-frequency regulation, the size of the centrifugal force in the classifier can be altered to achieve the goal of separating particles to the desired size.
