Manufacturing Process of Portland Cement TCL Blog

2014-8-26  The manufacture of Portland Cement takes place in a number of steps: At TCL's Mayo Quarry, limestone, one of the main ingredients in cement manufacture, is excavated. The limestone raw material then goes through several categories of 'crushing', until it is fine enough for water, sand and iron oxide to be added to produce a mixture known as Slurry.

11.6 Portland Cement Manufacturing US EPA

1971-8-17  The initial production step in portland cement manufacturing is raw materials acquisition.Calcium, the element of highest concentration in portland cement, is obtained from a variety ofcalcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impurelimestone known as "natural cement rock". Typically, these raw materials are obtained from open-facequarries, but underground mines or dredging operations are also used. Raw materials vary fromfacility to facility. Some quarries produce relatively pure limestone that requires the use of additionalraw materials to provide the correct chemical blend in the raw mix. In other quarries, all or part ofthe noncalcarious constituents are found naturally in the limestone. Occasionally, pockets of pyrite,which can significantly increase emissions of sulfur dioxide (SO2), are found in deposits of limestone,clays, and shales used as raw materials for portland cement. Because a large fraction (approximatelyone third) of the mass of this primary material is lost as carbon dioxide (CO2) in the kiln, portlandcement
