The material which can not pass through the screen 61 rolls to the lifting mechanism 700 through the slope 13, is lifted by the lifting mechanism 700 and then enters the feed hopper 11, and then enters the equipment again for crushing and screening. The crushed qualified materials fall into the discharge hopper 12 after passing through the screen 61. Collected by the discharge hopper 12 and then fed into the discharge pipe 300. When the metal foreign bodies are not detected, the plate turning mechanism 200 is tightly attached to the partition plate 36, and the materials fall down from the first blanking channel 31 and are discharged through the first discharge hole 33. When the metal foreign bodies are detected, the position of the plate turnover mechanism 200 is changed, the first blanking channel 31 is closed, the materials with the metal foreign bodies fall on the plate turnover mechanism 200, and then the plate turnover mechanism 200 rotates reversely to send the materials falling on the plate turnover mechanism into the second blanking channel 32, so that the materials flow out from the second discharge hole 34. Subsequently, the plate turnover mechanism 200 is immediately reset, continues to cling to the partition plate 36, and the material continues to flow out from the first blanking channel 31 and the first discharge hole 33, so that the separation of the metallic foreign matters in the material is realized.
