[0002] There are many types of industrial solid waste, and the grading and screening methods and equipment used for different types of industrial solid waste are different. When grading and screening some spherical industrial solid wastes such as spherical steel balls, it is mainly necessary to grade them multiple times according to their size, so that the steel balls can be fully separated after multiple grading and screening. The disadvantage of existing grading and screening equipment is that, since the existing equipment separates the large-sized ones first, and then gradually screens the small-sized spherical steel balls, it will cause the larger ones to be blocked on one side of the screening net, affecting the further screening of the smaller-sized spherical steel balls. People have conducted a lot of research on this. Utility Model Content
