[0026] The working principle of this embodiment is as follows:

[0027] When in use, the second motor 5 first controls the rotating blades 19 to stand upright, and then the aggregate is poured into the feed port 7 and the separation cleaning liquid is added. Then the first motor 4 drives the first stirring blades 16 and the second stirring blades 17 to rotate and stir, so that light-weight impurities, dust and dirt and other impurities are separated from the aggregate. Then the second motor 5 drives the rotating blades 19 to combine into a baffle assembly 18, and then the light-weight impurities, dust and dirt are discharged from the impurity outlet 10 and the liquid outlet 13 respectively. Then the aggregate passes through the discharge port 11 through the unloading assembly 3 and enters the air drying box 2 for air drying.
