[0033] During use, the material to be sorted is placed on the conveyor belt 201 for transmission, and the threaded column 203 is rotated by rotating the handle 206 to adjust the height of the fixed plate 204 and the magnet plate 205, so that the magnet plate 205 can absorb the ferromagnetic debris in the material transmitted on the conveyor belt 201. The unabsorbed material passes through the guide plate 207 on the conveyor belt and falls into the frame 1. The second hydraulic rod 9 is started, and the material can be pushed out of the frame 1 through the second push frame 10 for subsequent preheating and combustion.
