Quartz sand is a common non-metallic mineral raw material in the production. With the development of social demand for glass, there are two trends in the supply and demand of mineral raw materials in the glass industry.
One is that rapidly growing demand has led to a dwindling supply of qualified ore.The other is that the demand for raw ore is higher and higher, but the ore is poorer and poorer.
The demand of high grade and high grade materials has high requirement on the equipment of refining and dressing.In particular, iron removal equipment, for the impact of whiteness is crucial.
Hematite, limonite, ilmenite and amphibole are the main minerals containing iron in quartz sand, and their magnetic properties are very weak. Because the magnetic strength of ordinary magnetic separators cannot meet the requirements, it is difficult to remove them by magnetic separation.
The cost of pickling and flotation is too high, and it is easy to have problems due to environmental impact.So need a magnetic field intensity, high gradient, deep range of action, can remove weak mineral magnetic separator.
The high gradient magnetic separator is designed according to the market demand.It has high background magnetic field intensity, high magnetic field gradient, large concentration ratio, strong adaptability to feed particle size and concentration and taste fluctuation,
Intelligent operation control and other advantages, in the separation of weak magnetic ore to achieve high grade concentrate and high recovery of double high optimization.
