the production of cement

Cement Production an overview | ScienceDirect Topics

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017) Cementbased structures constitute the largest surface area of all manmade structures (Odigure, 2009)Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron oreHow Cement Is MadeEach of the raw materials is transported separately to silos, where it later will be added in specific amounts according to the particular type of cement being produced 6 Raw material mill This takes places in vertical steel mill, which grinds the material throughCement Production: How Cement Is Manufactured | CEMEX
