Slag utilization, more and more countries realize that slag is not a mere by-product, but a valuable resource, industrialized countries face a serious shortage of resources and lack of energy situation, but the steel slag processing and utilization of technology has be further developed. Slag comprehensive utilization rate of industrial countries has been rapidly improved, it has been a world leader in the ranks. Since diversification steelmaking equipment, process layout, slagging system, physical and chemical properties of slag.

slag recycling bring greater market space for steel slag vertical mill, steel slag mill is specially ground slag variety of special equipment, and materials to be grind before mixing interaction fineness required later, in order to make products to better strength, grinding is important processing in the aerated concrete production process, grinding process power consumption, slag vertical mill is usually the largest motor capacity equipment in aerated concrete plant .

the industrialized countries According to use of steel slag, steel-making process characteristics and help to improve the ability to choose steelmaking slag treatment process in order to protect the steel slag to enhance the comprehensive utilization.

The use of steel slag processing has a long history in foreign countries, in fact, slag can be used cement raw materials, road building materials, construction materials, fertilizers, soil conditioners. slag is also used Smelting to recovered slag active ingredient in calcium, magnesium, manganese, vanadium, iron oxides and rare elements, by saving a lot of limestone and fluorite, reducing coke, increase the utilization factor, cost reduction and other economic effects , several steel-producing countries in the world has always insisted on the use of blast furnace slag back, sintering, magnesium furnace solvent.
