[0002] Metallurgical converter slag is a by-product of the smelting process. After cooling, the converter slag forms particles, and the useful components can be effectively recovered by physical or chemical methods, such as recycling the metal components for re-smelting, and the non-metallic parts can be used as building materials. The particle recovery of converter slag mainly depends on physical screening methods, that is, through vibrating screens or other screening equipment, the particles are classified according to size to separate valuable materials.

[0003] However, the metallurgical converter slag resource recovery devices currently on the market generally have some defects. Existing devices often lack an effective particle classification mechanism, and use vibration motors for vibration screening, which causes great wear and tear on the equipment and requires frequent maintenance, which not only reduces the efficiency and benefits of resource recovery, but also increases operating costs and reduces the stability and reliability of the system.

[0004] Therefore, there is an urgent need for a resource recovery device for metallurgical converter slag to solve the technical defects proposed in the above-mentioned technology. Utility Model Content
