защита окружающей среды от виброг The crusher Help slag recycling of resources for sustainable development Slag, an industrial solid waste. The steelmaking slag discharged, according to the converter slag furnace is divided into flat slag, electric furnace slag. Discharge is about 15 to 20% of the crude steel prodгорно шахтное оборудование екатерuction. The slag after stone processing equipment, you can get reasonable use, land conservation to create a huge economic and social benefits. Currently, the Federal Republic of Germany, slag vast majority have been utilized. The United Kingdom, France, slag utilization of about 60%, about 10%. Slag uses ingredients. United States annually as 2/3 of the amount of slag the ironmaking flux, added directly to the blast furnace or join sinter, internal recycling of the steel plant. Component of the slag, in addition to silicon the useless and phosphorus harmful outer, calcium, iron, magnesium and manganese (of the slag 80% of total) were used. Of slag calcium, silicon, manganese, and trace elements are fertilising, as slag fertilizer applied to acidic soils. Various types of steel slag can be used as fill in the pits, land reclamation materials. ступенчатая мельница сверхдавленChina currently produces a small amount of slag cement, multi-purpose converter slag mixed about 50% of blast furnace granulated slag, gypsum about 10%, no clinker slag cement grinding, or instead of slag grinding cement clinker to 15% less clinker. In some places in China the EAF slag produced white slag cement. Japan, the Federal Republic of Germany, the use of slag as a cement raw material, the calcined ferrite cement, saving energy. In addition, stзащита окружающей среды от виброгeel slag manufacturing brick, tile, carbonized construction materials. A slag comprehensive utilization, crushed slag stone equipment I baked dry magnetic separation screening, finely ground crushed grading, the wet magnetic classification, pellets manufacturing processes. The advantage is that all the effective use of steel mill slag can get with no waste, solve the ills of steel mill slag possession of a large number of farms and land, causing great environmental pollution, and bring great social benefits to the community and economic benefits. China is the world's first steel-producing countries, will naturally produce slag and other industrial waste, all the slag recycling, not only to reduce industrial emissions, can also play a savings of arable land, turning waste into recycling sustainable development. ?
