Wet Process of Cement Manufacturing AGICO Cement Plant

The dry process of cement manufacturing means that after raw materials with different particle sizes are dried, broken and ground into powders of certain fineness, they will be sent into the dry process kiln for calcining, finally forming clinker. Besides, the raw material powder can also be made into raw material balls by adding a proper amount of water and then be directly sent to the Lepol

Cement: Materials and manufacturing process

• Chalk is porous and often has high moisture content that leads it to its use in the ‘semi-dry/wet’ manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones.
