1.Blast Furnace Slag Application
Blast furnace slag application: Blast furnace slag can be processed into a variety of valuable materials with multiple uses. Processed into slag gravel can replace natural sand as concrete,reinforced concrete and prestressed concrete below No. 500 aggregate;As the auxiliary materials ofconcrete aggregate operating temperature below 700 ℃ heat, requiring abrasion resistance,slip ofthe highway, Speedway , runways and other auxiliary materials;AS railroad ballast,to fill trenches and foundation cushion filler,sewage treatmentand other media. Blast furnace slag fine with plenty of water after water quenching,can be made m ainlycontaining vitreous, a potential hydraulic cementitious properties in cement clinker, lime, gypsum and other activator effect, show water coagulation performance,high-qualitycementraw materials.China's production of cement,70% to 80% mixed with different amounts ofwater residue.Slag fine aggregate insulation material also for families,wetgrinding and wet slag,concrete and road works;soil improvementmaterials. Hot meltslag can be processed into porous expanded slag,by crushing, sieving become lightweight aggregate concrete,can be processed into containing porous,smooth surface,the particle sizes-expandable beads. Expandable beads are high quality light weight aggregate concrete,slag expansion ratio can save 20% of cement;cementmixing materials can be made,road materials,insulation materials. Blowing with compressed air or high pressure steam injection flow ofhot meltslag,slag wool can be prepared.As insulation,sound absorption,fire prevention materials and other purposes. In addition. blast furnace slag can be used as raw material caststone, glass, fertilizer, enamel, ceramic, etc..
2. Blast Furnace Slag Vertical Grinding Mill
Blast furnace slag is a waste slag discharged from smelting of pig iron blast furnace. When smelting pig iron in the blastfurnace,we need add iron ore and fuel (coke), a flux. When the furnace temperature reached 1400 to 1600 ℃, the flux react with iron ore and produce pig ore and slag. Blast furnace slag composes ofgangue,ash,flux and other impurities thatcan not enter iron ore, is a kind of eutectic mixture. Blast Furnace Slag Ultrafine Vertical Powder Grinding Mill, the fineness can adjusted from D97=30 mesh to D97=2500 mesh,capacity and get 1-30 t/h. Blast furnace large capacity vertical grinding mill, the capacity can get 10-400 t/h.
