Principle of stainless steel grading wheel operation: 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 descend to the crushing area for further crushing.

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

The air-powder mixture entering the classifier first goes into the classifier wheel, where under the force of centrifugal force, larger or heavier particles experience greater centrifugal force and are thrown to the outer edge of the classifier wheel and the side wall, no longer influenced by centrifugal force, and fall naturally into the粉碎 main machine for further crushing or drop to the discharge port for collection. Lighter or smaller particles are less affected by centrifugal force, hover inside the classifier wheel, and are carried to a higher position by the induced draft fan's force, flowing through the pipeline to the next component where they are separated or collected. Adjusting the classifier wheel's speed by means of variable-frequency regulation can modify the centrifugal force in the classifier, achieving the goal of separating particles to the desired size.
