The height of the partition plate can be adjusted specificto the separating requirements of light impurities; the electric stirring equipment of the feeding inlet is mainly used for preventing building waste from blocking the feeding inlet and meanwhile enabling the building waste to be evenly spread, and thus air separating achieves the better effect; and the air supply opening adjusting device is mainly used for adjusting the air supply angle of the air supply opening, so that the optimal air separating effect is achieved.
