The air flow in the wind distribution box 61 flows out from the wind distribution openings 612 of each wind distribution cavity 614 after being guided by the wind distribution plates 613. The air flow flowing out from the wind distribution openings 612 blows towards the screening frame 21 through the wind guiding boxes 62, so as to perform specific gravity screening on the lithium battery materials.
