The eddy current inlet pipe is externally connected to an eddy current fan, and the silicon micropowder falls into the second material distributing wheel. The first material distributing wheel and the second material distributing wheel are driven to rotate by a servo motor. Since the silicon micropowder collides with the alumina balls after falling into the second material distributing wheel, and the hardness of alumina is higher, the coarse blocks of silicon micropowder can be collided and crushed, so that the silicon micropowder is thrown into the inner wall of the second material blocking plate and is collided and crushed again by the alumina blocks.

[0020] As Figures 1-3A classification device for silica powder processing as shown, the classification component 5 includes a first material distribution wheel 501. A second material distribution wheel 502 is placed on the upper surface of the first material distribution wheel 501. The second material distribution wheel 502 is provided with a plurality of alumina balls.

The first material distribution wheel 501 and the second material distribution wheel 502 are driven to rotate by the servo motor 2.
