[0020] In this embodiment, the slag is transported to the interior of the ball mill 1 by a conveyor, and the ball mill 1 feeds the material to the surface of the discharge plate 2 for sliding. During the sliding process, the first rotating motor 6 is connected to an external power supply to drive the first screening roller 5 to rotate. Since the first screening roller 5 is magnetic, the iron powder in the slag can be adsorbed for a first screening. At the same time, a second screening roller 8 can be set for a second screening for further adsorption. This design method can effectively adsorb and screen the iron powder contained in the slag through two magnetic separation adsorptions, and can effectively recover the iron powder in the slag for reuse, saving resources.

[0021] Specifically, a cleaning water pipe 10 is fixedly connected to one side of the first fixing ear 4 and the second fixing ear 7 . A water outlet hole 11 is fixedly opened on the surface of the cleaning water pipe 10 . The number of the water outlet holes 11 is several.

[0022] In this embodiment, the cleaning water pipe 10 is provided, and when an external water source is introduced at one end, the first screening roller 5 and the second screening roller 8 can be cleaned to avoid impurities such as iron powder and dust remaining on the surface after long-term use.

This design method can perform vibration discharge, which is conducive to evenly separating the slag, so that sufficient magnetic adsorption can be performed, so that the iron powder can be fully removed.
