Which part of the ore mill can be used for quicklime sleeves
Lime, an essential component in the steel industry
At the top of the furnace the iron ore in pellet form, together with the coal or coke and limestone (CaCO3) or quicklime (CaO), are introduced whilst at the bottom hot air is added with the aim Dolomitic quicklime is used to produce metallic magnesium by thermal reduction which reduces magnesium oxide Lime is also used in the processing of ores and the subsequent smelting QUICK LIME AND BYPRODUCTS PEC Consulting GroupQuicklime both high calcium and dolomitic enjoys its most extensive use as a flux in purifying steel in the electric arc furnace (EAF) and basic oxygen furnace (BOF) Lime is particularly Iron and Steel Limeprimary mill for grinding coarse ore directly from the crushed stockpile Such application requires a more aggressive liner profile with high lifter bars and relatively thin intermediate plates This Three factors that determine the wear life and performance of mill
