Stainless steel grading wheel working principle: Under the force of the fan's suction, the material moves with the rising air flow to the grading area. Driven by 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 within the grading housing (speed can be adjusted as desired), creating a powerful centrifugal force within the grading machine.

The gas-powder mixture entering the classifier first goes into the classifier wheel. Under the action of centrifugal force, larger or heavier particles experience greater centrifugal force and are thus thrown to the outer edge of the classifier wheel and the side wall, where they no longer feel the centrifugal force and naturally fall into the crushing main body for further crushing or drop to the discharge port for collection. Smaller or lighter materials experience less centrifugal force and hover within the classifier wheel. Influenced by the suction force of the induced draught fan, they are carried to a higher position and then flow through the pipeline to the next component where they are classified or collected. By varying the speed of the classifier wheel through frequency conversion, the size of the centrifugal force in the classifier can be adjusted, achieving the goal of separating particles to the desired size.
