Wind and magnetism combination type iron separator

Abstract

The invention relates to a wind and magnetism combination type iron separator. The wind and magnetism combination type iron separator comprises a box body, wherein a feeding opening, a residue discharging opening and an iron discharging opening are formed in the box body; a roller is arranged in the box body, and a central shaft matched with the roller is arranged in the box body; the two ends of the central shaft are fixed to supports arranged in the box body; the roller is driven by a power device to rotate; a magnetic system distributed in an arc shape is arranged in the roller along the circumference, and a wind inlet and a wind outlet are arranged on the roller; the feeding opening is positioned at the upper part of the box body, and the bottom end of the feeding opening is positioned in the magnetic force range of the magnetic system; the iron discharging opening is positioned at the bottom of the box body and is positioned in the non-magnetic-force range of the magnetic system; and the residue discharging opening is positioned at the bottom of the box body and is positioned in the magnetic force range of the magnetic system. According to the technical scheme, through guiding wind into the separating process, the separating effect is improved, and the grade of separated iron is improved, so that the part of iron can be directly utilized; and the subsequent technical process is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to an iron remover, in particular to an air-magnetic compound iron remover for a steel slag grinding system. Background technique [0002] my country is a big iron and steel country, and the steel slag produced by steelmaking is about 100 million tons every year. Steel slag is rich in valuable elements such as Ca, Si, Fe, Mg, A1, etc., and contains a lot of heat energy. It is a valuable secondary resource. Effective treatment and utilization of steel slag is not only conducive to energy saving and consumption reduction, but also to reducing greenhouse gas emissions. It is also the only way for iron and steel enterprises to achieve sustainable development and circular economy. After the steel slag is finely ground to fine powder, the crystal structure of the steel slag is mechanically destroyed, the surface energy and potential activity are partially released, the stability is completely resolved, and it can be used as a buildin...

AI Technical Summary

Problems solved by technology

At present, the commonly used pipeline iron remover only relies on magnetic force and the gravity of the material itself for separation, which often has the problem of low separation efficiency. Part of the iron will enter the mill with fine-grained steel slag, thereby increasing the energy consumption of the mill. The content of iron in the finished product is often Also higher; part of the steel slag powder will also be selected together with the iron, resulting in the low grade of this part of iron, which cannot be directly recycled
