Steel slag magnetic separation device

The invention provides a steel slag magnetic separation device. The steel slag magnetic separation device comprises a rack, a separation sleeve, two annular isolation plates, a magnetic device and a first shielding plate. And the sorting sleeve is rotatably arranged on the rack. The two annular isolation plates are parallel to each other, and the inner rings of the two annular isolation plates are connected with the outer circumferential wall of the sorting sleeve. And the magnetic device can magnetically attract the steel slag with ferromagnetism between the two annular isolation plates to the annular isolation plates from the outer sides of the two annular isolation plates. A sorting channel is formed among the first shielding plate, the two annular isolation plates and the outer wall of the sorting sleeve. Steel slag is often mixed with other solid wastes and is easily extruded after being crushed and magnetically separated, so that the screening effect is poor. According to the device, the steel slag is o
