The baffle plate 44 moves away from the air guide cover 35. When the baffle plate 44 descends to the designated position, some steel slag flows onto the screen of the vibrating screen 1. Subsequently, the drive motor 41 continues to adjust the baffle plate 44 downwards, and the steel slag continues to slide onto the screen of the vibrating screen 1. By setting up the feeding device 4, the operator can effectively control the amount of steel slag fed, avoiding poor screening results when a large amount of steel slag rolls on the screen of the vibrating screen 1, thereby improving the screening effect of the screening device.
