Powdered waste is screened out through the inclined screen plate 5. The meshing of the conveying worm gear 19 and the driven worm wheel 20 drives the fixed shaft 21 to rotate. The rotating crossbar 22 on the fixed shaft 21 drives the shifting shaft 23 to rotate. The shifting shaft 23 drives the magnetic block 24 to move through the adjustment through hole 25. During the movement, the magnetic block 24 adsorbs the ferromagnetic waste that passes by, separating it from other waste and realizing the recycling of magnetic waste.
