[0027] The aluminum scraps enter the blanking hopper 1 through the feeding unit. The pneumatic conveying component makes the air in the blanking hopper 1 flow towards the direction of the pneumatic conveying pipeline 3. The aluminum scraps in the blanking hopper 1 flow along the pneumatic conveying pipeline 3 under the dual action of gravity and wind force and enter the air-material separation component, so as to separate the gas from the aluminum scraps. The separated aluminum scraps are conveyed to the aluminum scrap melting furnace 10 through the horizontal transportation component for melting.
