Therefore, a feed screening device is proposed to facilitate the screening of different feeds, so that workers can collect them in a centralized manner. At the same time, the small amount of moisture carried in the feed can be dried to avoid agglomeration, which is convenient for rapid screening and improves processing efficiency.
