Steel slag mainly arises from the oxidation of elements contained in the molten iron and scrap; metal impurities; the slag agent including limestone, fluorite, silica, as well as oxidants, desulfurization products and the erosion of lining materials.
The main the different parts of steel slag are calcium, iron, silicon, magnesium, aluminum, manganese and phosphorus oxides. The primary standby time with the slag are as follow. First, it may be as an alternative to lime being a solvent to come back the blast furnace or sintering furnace working itself. It can be utilized for roadbed, railway embankment, and as cement raw material, soil, etc.
The processing technology of steel slag are cold abandoned law, hot pour method, splashing cold plate method and slag water quenching method. Generally a closed loop production process is going to be used. And that we will get four high-quality as well as value-added products from the means of crushing and screening, vacuum ball milling, dry magnetic separation and classification processes of wind. The four goods are respectively high-quality steel scrap, high-grade iron powder, steel slag powder utilized as cement, the steel slag aggregate used as asphalt concrete surface layer within the road. After completion of the entire production process, slag may be accomplished zero emissions, as well as the environment pollution with the slag is completely solved.
Many engineering machinery companies specialize in producing ultra-fine grinding and screening equipment for steel slag processing. For instance, the ecu version jaw crusher, hydraulic cone crusher, Symons cone crusher, impact crusher, LM vertical milling machines along with other equipments. In China, one company has established a successful steel slag crushing magnetic line which could handle A million plenty of slag. To get the targets of needing all of the slag processed, recycling, circular economy, emissions-reduction, another company invested eight million yuan (about $123,0000) over a steel slag crushing magnetic line. And they purchased jaw crusher, cone crusher and Symons cone crusher from engineering machinery company. New production line was designed and installed by them.
