Blast furnace slag granulation ClimateTechWikiHow Cement Is Made

One way to reduce energy and process emissions in cement production is to blend cements with increased proportions of alternative non clinker feedstocks such as volcanic ash granulated blast furnace slag from iron production or fly ash from coal fired power generationCement is so fine that 1 pound of cement contains 150 billion grains The cement is now ready for transport to ready mix concrete companies to be used in a variety of construction projects Although the dry process is the most modern and popular way to manufacture cement some kilns in the United States use a wet process

Manufacturing Skyway CementSteel Slag Usage in Cement Industrial Efficiency

THE PROCESS Manufacturing Skyway Cement requires two basic processes granulation and grinding Granulation This process transforms molten slag into granul Skyway Cement receives granulated slag from a US steel manufacturer in Gary IndianaAbout 100 200 kg of BOF slag is generated per ton of liquid steel This material is often used in projects like road construction but this route provides little energy efficiency gains Steel slag can also be used in the cement clinker manufacturing process The result is an increase in clinker production of up to 15 with no net increase in CO2 emissions
