In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water. Dry and semi-wet processes are more energy-efficient. The wet process requires 0.28 tons of coal and 110 kWh to produce one ton of cement, while the dry process requires only 0.18 tons of coal and 100 kWh of energy [4] .
Materials used to produce portland cement
A. The two principal materials from which portland cement is made are a material of high lime content, such as limestone, chalk, shells, or marl, and a material of high silica and alumina content such as clay, shale, or blast-furnace slag. A small amount of iron is also needed. Sometimes the principal materials are combined in naturally ...
What Is Cement Made Of?
Then, hot gas and fine materials enter a multistage "cyclone". This separates fine ground material from its gases. The resulting very fine raw material is conveyed to a silo. From there the raw material, now called kiln feed, is fed to the top of the kiln for sintering. Raw materials are cooked and turned in a kiln at approx. 1,450°C.

CEMENT RAW MATERIALS
The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level
Raw materials
Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending. Most of the material is usually ground finer than 90 microns - the fineness is often expressed in terms of the percentage retained on a 90 micron sieve. Once the the raw materials are ground fine enough, they are blended in ...
