After the electromagnet 604 on the adsorption mechanism 6 is energized, it will adsorb the magnetic metal in the crushed building materials to recover the magnetic metal, and the magnetic metal will be discharged from the discharge port 5 below the retaining frame 706, while other crushed building materials will be discharged through the discharge port 5 on the other side, and the crushed building materials will be classified and recycled.

[0024] like Figure 3As shown, the adsorption mechanism 6 includes a driving shaft 601 movably mounted in the bearing groove 3, a rotating wheel 605 is fixedly mounted on the driving shaft 601, an electromagnet 604 is fixedly mounted on the rotating wheel 605, the adsorption mechanism 6 also includes a connecting wire 602 connected to both ends of the electromagnet 604 and a mounting groove 603 opened on the surface of the rotating wheel 605, a conductive voltage plate 607 is fixedly mounted at the end of the connecting wire 602, and the conductive voltage plate 607 is pressed on the graphite ring 703, and a driving motor 606 is fixedly mounted on the surface of the pulverizer body 2.

[0025] Specifically, the driving motor 606 will drive the driving shaft 601 to rotate, thereby causing the rotating wheel 605 to rotate inside the pulverizer body 2. When the rotating wheel 605 rotates inside the pulverizer body 2, the crushed building materials will fall onto the surface of the electromagnet 604.
