Description

Technical Field

[0001] The utility model relates to the field of iron ore slag processing, in particular to an iron ore slag processing production line. 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 temperatures, and impurities such as silicon dioxide and aluminum oxide in the iron ore react with lime and other substances 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;

[0003] The prior art CN201510596771.6 connects one end of the main bracket to the inner wall circumference of the roller support body by bolts, and the other end to the inner wall circumference of the drum tail body by bolts. Connect one end of the longitudinal frame to the inner circumference of the drum support body by bolts, and the other end to the inner wall circumference of the drum tail body by bolts. Through such connection, the self-joined mechanism of the longitudinal frame, the auxiliary bracket and the screen mesh achieves a similar seamless connection effect with the drum support body and the drum tail body. There is no gap to fill in the scattered iron slag, which is more conducive to the screening of the iron slag. However, the size of the sieve hole inside the screening structure in the above device is the same, and the iron slag is only screened once, and the screening effect is not good. In addition, the production process of the iron slag needs to be extracted and processed. During the processing, the iron slag has different sizes, and the effect is poor when reacting with the reaction liquid, resulting in a significant reduction in the processing efficiency of the entire processing production line.
