Technical Field

[0001] The invention relates to the technical field of slag grinding and utilization, in particular to a slag ultrafine grinding and screening device. Background Art

[0002] Slag is a by-product of the blast furnace ironmaking process. During the ironmaking process, iron oxide is reduced to metallic iron at high temperature, and impurities such as silica and alumina in the iron ore react with lime to form a molten material with silicates and aluminosilicates as the main components. After quenching, it becomes a loose, porous granular material, which is blast furnace slag, referred to as slag.

When the slag needs to be ground and screened, the staff only needs to put the material to be ground and screened. The ground slag is poured into the crushing box 3, crushed by the crushing body 4, and falls onto the screening plate 6 inside the box body 1. At the same time, the vibration device 13 is started to screen the crushed slag on the screening plate 6. At the same time, the dust removal component 5 is used to discharge the dust generated when screening the slag on the screening plate 6. The powder screened by the screening plate 6 falls into the first collecting box 71 below the inverted screening plate 6 for storage. At the same time, the dust reduction component 8 is used to perform dust reduction treatment on the powder collected in the first collecting box 71, thereby effectively reducing the dust in the first collecting box 71. At the same time, the powder in the first collecting box 71 is also cleaned, effectively improving the quality of the collected powder.

[0031] A first support plate 14 is fixedly connected to the waste port on one side of the box body 1, and a first slide 15 is provided on the lower surface of the first support plate 14.
