[0002] The traditional sintering ore production process is to mix and granulate various iron ore raw materials, flux and fuel, and then distribute them to the sintering machine for automatic sintering through ignition and ventilation. After the sintered sintered cakes are crushed, cooled and screened, about 80% of the parts larger than 5mm are sent to the blast furnace as finished products, and about 20% of the small particles below 5mm and dust are returned to the sintering batching system as return ore, and then secondary sintering is carried out.

[0003] Existingly, when sintered ore particles are screened, the sintered ore particles are poured into a graded screen device, and then the graded screen device is used to screen the sintered ore particles, so that the sintered ore particles are screened in multiple stages; however, when the graded screen device is screening the sintered ore particles, the sintered ore particles will be stuck in the gap of the screening plate, so the operator needs to operate to clean them, which makes it more cumbersome to clean the sintered ore particles on the surface of the screening plate and inconvenient to use. In view of this, we have introduced a graded screen device for sintered ore particles. Utility Model Content
