In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
Cement Plant Manufacturing Process Understanding Of Cement Process Most Common materials which is used to manufacturing cement is includes limestone, shells, and chalk combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

According to the EU, portland cement clinker is a hydraulic material which shall consist of at least twothirds by mass of calcium silicates (3 CaO·SiO2 and 2 CaO·SiO2), the remainder consisting of aluminium and ironcontaining clinker phases and other compounds.
cement process. The manufacture of cement is a very carefully regulated process comprising the following stages: Quarrying a mixture of limestone and clay. Grinding the limestone and clay with water to form slurry. ... Grinding the clinker with about 5% gypsum to make cement.
Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient.
