The invention belongs to the field of fertilizer raw materials and discloses a device for recovering metal chips in fertilizer raw materials. The device comprises a separation container, a recovery channel and a raw material channel. The separation container is formed by a bottom plate, a left side plate and a right side plate. A switch and a first valve are arranged on the left side plate, the first valve is located below the switch, and the recovery channel is connected with the first valve. A filtering screen is arranged on the side wall, away from the switch, of the recovery channel, and an electromagnet is arranged at one end, away from the first valve, of the recovery channel and is electrically connected with the switch. A chip channel is arranged between the electromagnet and the filtering screen, a sliding plate is fixed to the chip channel slantwise and abuts against the electromagnet, and the chip channel is communicated with the recovery channel. A second valve is arranged on the bottom plate, the raw material channel is connected with the second valve, a return pipe is connected between the filtering screen and the raw material channel, and the return pipe, the recovery channel and the raw material channel are communicated. By means of the scheme of the device, labor intensity of workers can be reduced, and production efficiency is improved.
