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.

Cement Interesting Facts - נשר מלט
There are three common methods for manufacturing cement: the wet process, which is the oldest traditional method; the semi-dry method; and the dry method. The main difference between these methods is the amounts of water added to the raw materials prior to entering the kiln. The less water used, the greater the energy efficiency and thus the ...

CEMENT RAW MATERIALS - International Cement Review
2013-6-9 Over recent decades there has been a move away from the wet process to the more energy efficient dry process. In Europe, for example, about 78% of cement production is from dry process kilns, a further 16% of production is accounted for by semi-dry/semi-wet kilns, and only about 6% of European production now comes from wet process kilns.
