Crusher Machine For Recycling of Steel Slag

 

Steel slag mainly comes from the oxidation of elements contained in the molten iron and scrap; metal impurities; the slag agent including limestone, fluorite, silica, along with oxidants, desulfurization products and the erosion of lining materials.

The key pieces of steel slag are calcium, iron, silicon, magnesium, aluminum, manganese and phosphorus oxides. The main technique slag are as follow. First, it is usually instead of lime like a solvent to send back the blast furnace or sintering furnace in the catering company itself. It's also used for roadbed, railway embankment, in addition to being 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. So we will get about four high-quality and high value-added products by the procedure for crushing and screening, vacuum ball milling, dry magnetic separation and classification processes of wind. The four items are respectively high-quality steel scrap, high-grade iron powder, steel slag powder used as cement, the steel slag aggregate utilized as asphalt concrete surface layer inside the road. After finishing the entire production process, slag can be carried out zero emissions, as well as the environment pollution from the slag is totally solved.

Many engineering machinery companies focus on producing ultra-fine grinding and screening equipment for steel slag processing. As an example, the eu version jaw crusher, hydraulic cone crusher, Symons cone crusher, impact crusher, LM vertical milling machines and also other equipments. In China, one company has produced a successful steel slag crushing magnetic line which may handle One million plenty of slag. To achieve the targets of having all of the slag processed, recycling, circular economy, emissions-reduction, another company invested 8 million yuan (about $123,0000) with 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 made and installed by them.
