Blast Furnace Slag Application and Vertical Powder Grinding Mill www.vertical-mill.net

1. Blast Furnace Slag Application and Vertical Powder 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 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 Yingjiao 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 qualitylightweightaggregate 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..
