Stainless steel grading wheel working principle: Under the force of the fan's suction, materials move with the rising air flow 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 fall to the crushing area for further crushing.

The motor drives the stainless steel grading wheel to rotate at high speed (speed is adjustable) within the grading housing, creating a strong centrifugal force within the grading machine.

The gas-powder mixture entering the classifier first goes into the classifier 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 classifier wheel and the 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 classifier wheel and are carried to a higher position by the induced draft fan's force, then smoothly flow through the pipeline to the next component for classification or collection. The size of the centrifugal force in the classifier can be adjusted by varying the speed of the classifier wheel through frequency conversion, achieving the goal of separating particles to the desired size.
