for clinker production, the raw materials are often preheated - to enable the chemical reactions to occur quickly and efficiently in the kiln - and calcined (calcinations) to separate calcium oxides from calcium carbonates contained in the raw materials. During the process, significant amounts of carbon dioxide (CO 2) are released. In the kiln system, calcium oxides are sintered at a typical ...
Portland cement clinker - overview - Understanding …
Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.
