During the use of the existing screening device, only a filtering frame is used for screening work, which not only has low efficiency but also poor screening effect. Moreover, during the screening process, the filtering frame cannot quantitatively feed the ore, but all the ore is put into the screening frame, which is likely to affect the screening efficiency.
