Clinker Production
Clinker sintering is a crucial link in clinker calcination, which mainly occurs in the cement kiln. Inside the kiln, raw meals are heated by rising temperature and generate a series of physical and chemical reactions. When the temperature reaches its peak, the clinker will be produced by rapid cooling. These reactions can be expressed as follow：

New approach suggests path to emissions-free cement
Caption: In a demonstration of the basic chemical reactions used in the new process, electrolysis takes place in neutral water. Dyes show how acid (pink) and base (purple) are produced at the positive and negative electrodes. A variation of this process can be used to convert calcium carbonate (CaCO3) into calcium hydroxide (Ca(OH)2), which can then be …

What is Cement Clinker? Composition, Types & Uses
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
3.1 CO2 Cement Production
significant source of global carbon dioxide (CO2 ) emissions, making up approximately 2.4 percent of global CO2 emissions from industrial and energy sources (Marland et al., 1989). Cement is produced in large, capital-intensive production plants generally located near limestone quarries or other raw carbonate mineral sources as
