[0030] In this embodiment, when the steel slag is conveyed to the right on the conveyor belt body 2, it will pass through multiple magnetic separation rollers 5. Under the action of the multiple magnetic separation rollers 5, the iron content in the steel slag can be effectively reduced, thereby improving the recovery effect.

[0031] A lower material baffle 9 is provided on the left side of the first conveying baffle 3 and the left side of the second transmission baffle. In the present embodiment, the lower material baffle 9 can prevent the material from scattering.

[0032] A first discharge port 10 and a second discharge port 11 are positioned opposite each other at the bottom of the trough 6.
