Stainless Steel Grading Wheel Working Principle: Materials are moved upwards in the air current under the force of the fan, and then separated into coarse and fine particles in the grading area due to the strong centrifugal force generated by the high-speed rotating grading turbine. Fine particles that meet the particle size requirements pass through the grading wheel and enter 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 freely), generating a strong centrifugal force within the grading machine.

The gas-powder mixture entering the grading machine first goes into the grading wheel. Under the action of centrifugal force, larger or heavier particles are subjected to greater centrifugal force and are thrown to the outer edge of the grading wheel and the side wall of the grading machine, where they are no longer affected by 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 and hover inside the grading wheel, influenced by the induced draft fan's airflow, which carries them to a higher position and then moves along the pipeline to the next component where they are graded or collected. By adjusting the speed of the grading wheel through frequency conversion, the magnitude of the centrifugal force in the grading machine can be controlled, achieving the goal of separating particles to the desired size.
