With the globalization of the development of economy, many companies are forced to improve the competitiveness of their products by means of saving energy, reducing consumption, increasing efficiency, etc.

Being a basic industry, this high-energy-consumption metallurgy industry faces great pressures and challenge as other industries as well. The main method of saving energy, reducing consumption and increasing efficiency is to put the beneficiated burden materials in kilns. It has been testified by practice that with the 1% increasing of the grade of iron concentrate, the coke ratio can be reduced 2% and the production can be increased 3%. Since the iron ores in our country are of different kinds and fine-grained dissemination, the grade of iron concentrate has been always lower, with the Si content being higher. Thus, the methods to improve the quality of iron concentrate has aroused high attention among our native enterprises and mining scientists, who have made a large number of researches and developments from ore-dressing crafts to ore-dressing equipments.

From the aspect of the magnetic separator equipments, the BKJ Type Magnetite Sorting Machine, BKB type and BX Type Multi-face Permanent Magnet Cylindrical Magnetic Separator, as well as More-forces Sorting Equipment have been carried out. These researches and developments have improved the quality of the iron concentrate greatly, which have promoted the progress of iron ore separator crafts at the same time.

Some improvements have been done on the traditional cylindrical magnetic separator. The weak magnetic field equipment research is still mainly on the permanent magnet cylindrical magnetic separator, while large numbers of researches and experiments had been made on the ways of feeding ore, abrasive resistance of the cylindrical appearance and structures of the chutes, with the most two outstanding researchers being a certain domestic mine research institute and an American magnetic companies, who have made some researches on the techniques of resistance to surface wear, in addition to design and product the Double Stainless-Steel Cylindrical Skin Magnetic Separator. Another improvement is to install a valve on the tube beneath the chute, used to expel the tailings, of the magnetic separator, which can adjust the height of liquid level.
