typical process of manufacturing cement clinker in the cement

Cement manufacturinghas several opportunities for WHR, specifically in theprocess stepwhere theclinker materialis produced. Forclinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C.

Gypsum controlthe setting properties of the cement. It can be partially replaced by other forms ofcalcium sulfate. Some technical conditions allow adding other materials. A typical clinker has an approximate composition:CaO -67%, SiO2 – 22%, Al2O3 – 5%, Fe2O3 – 3%, and 3% of other components.

Apr 03, 2020· The cement manufacturing process involves several key steps, including preparing the raw materials, grinding the materials together, heating the newly formed clinker in a kiln, and finishing the cement with fine grinding. Some of the main ingredients used to make cement include limestone, clay,shale,iron, and sand. Different manufacturing techniques will use either wet ordry grinding, but each …

Theclinkeris ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush theclinkerinto a super-fine powder. It can now be considered Portlandcement. Thecementis so fine it will easily pass through a sieve that is fine enough to hold water.
