Cement: Materials and manufacturing process

• Carboniferous limestones are the major source of raw material in Britain. The other main limestones are Cretaceous (Chalk) and Jurassic. • 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

Cement Kilns: Size Reduction and Grinding

The ancient observation that hard materials were easier to grind in a liquid medium led to the use of "wet process" grinding of raw materials in the cement industry, and grinding by this technique was always much more energy-efficient than dry grinding, although the energy required to remove the water from rawmix was always vastly greater than that saved during grinding.
