Apr 27, 2020· Pfeiffer said the mill will grind slag and cement to afineness of between 3000 and 3800 blaine at a rate of between 235t/hr and 340t/hr.It says the mill improves plant availability by the active redundancy of the grinding rollers, enabling mill operation with reduced rollers in the event of maintenance work or a malfunction
Slag cement isa hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable finenessand is used to replace aportion of portland cement.It is a recovered industrial by-product of an iron blast furnace
Feb 07, 2021· Slag cement, often called ground granulatedblast-furnaceslag (GGBFS), isone of the most consistent cementitious materials used in concrete.It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace
Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design

Slagpowder is high-performing admixture forconcretein that it increases theconcrete’s ability to resist compression, tension, shear, and bending stresses. A major trend that characterizes the building material industry is to replace equal amount ofcementwithslagpowder in makingconcreteorcementproducts
To dry theslagwhilegrinding, we need hot air, which is present in the mill at around 200°C. This is supplied by a burner from Loesche. The fuel is predominantly blast furnace gas, a byproduct from the blast furnaces that is high in carbon monoxide (CO)
Slagis mainly used for the production ofcement, either as acementmixture, can also be made non-clinkercement. After finegrindingblast furnaceslagcan be used as the main raw material for the production ofslagpowder. It can replace silicon bath soil insulation packing and save cost
