Iron ore is an important raw material for iron and steel production enterprises, is a mineral aggregate containing iron simple substances or iron compounds capable of being economically utilized, and all ores containing iron elements capable of being economically utilized are called iron ore. The iron ores are various in types, and magnetite, hematite, siderite and the like are mainly used for iron making, wherein rich ores can be directly put into a smelting furnace for smelting, and lean ores or iron ores with more harmful impurities need to be subjected to ore dressing. The natural iron ore is crushed and ground during mining, impurities can be removed through methods such as magnetic separation, flotation, gravity separation and the like, and iron is separated, wherein a magnetic separation impurity removing machine is needed in the process of magnetic separation impurity removal.

When the existing magnetic separation impurity removing machine is used for carrying out magnetic separation impurity removal on iron ores, magnetic iron ores are generally screened out through magnetic components, and then the screened iron ores are scraped through a scraper. However, because iron ore can pass through broken handle before the edulcoration, the iron ore granule when consequently the edulcoration is less, and the iron ore of tiny particle passes through magnetism and permanent magnetism cylinder and firmly adsorbs together, only is difficult to thoroughly scrape iron ore completely through the scraper blade, has a large amount of iron ore powder firmly to adsorb on magnetic part after using for a long time, makes some positions of magnetic part bodiness gradually, and weight also can greatly increased, finally can influence the normal operating of equipment. In addition, when the iron ore powder is scraped from the magnetic component by the scraper, the iron ore powder can cause great abrasion to some parts of the magnetic component, the magnetic component can be damaged after long-term operation, the magnetism is reduced, and the magnetic separation operation is influenced.

For example, the Chinese patent application number is: CN202122825575.5, published as: patent document 6/24/2022 discloses a magnetic separation and separation device for iron ore, which screens magnetic iron ore by a magnetic permanent magnet roller and scrapes the iron ore from the permanent magnet roller by a scraper. Therefore, the device is when carrying out the magnetic separation edulcoration to broken iron ore, has a large amount of iron ore powder absorption on permanent magnetism cylinder after the long-time use mentioned promptly, makes permanent magnetism cylinder weight increase to and the damaged and magnetism reduction in permanent magnetism cylinder position, the normal operating's of final influence equipment problem.
