cement clinker manufacturing process
Production Process | CEMEX Philippines
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. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.

Cement Clinker
The incorporation of SSA into the manufacturing process has been found to significantly increase the P 2 O 5 and SO 3 contents in the resultant cement clinker. At the higher end of the tested SSA levels, these oxide contents become excessively high and this generally appears to suppress the formation of C 3 S, which is the mineral phase ...

Understanding the Role of Clinker Grinding in Cement Production
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.

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 ...
