Portland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
Other articles where Wet process is discussed: cement: Manufacture of cement: .manufacture are known as the wet, dry, and semidry processes and are so termed when the raw materials are ground wet and fed to the kiln as a slurry, ground dry and fed as a dry powder, or ground dry and then moistened to form nodules that are fed to.
The pellets are baked hard in a preheating grate by means of hot gases from the kiln. The pellets then enter the kiln where temperature is about 1450°C. The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.
From the limestone quarry to the delivery of the end product, follow every step in the cement manufacturing process. Step 1: extraction of raw materials The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay.

This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the '' Clinker '' pages.
Aug 27, 2015· Cement Manufacturing Process August 27, 2015 S. C. Rangwala Cement, Construction Material 0 The entire manufacturing process in a modern plant is now controlled through a microprocessor based programmable logic control system to maintain uniform quality of cement and a high rate of production.
The cement manufacturing is done by majorly by two methods known as wet process and dry process depending on their mixing is done with water or without water. The wet process of cement manufacturing too popular for several decades because of the possibility of more accurate control while raw material mixing.
What Are the Differences Between the Wet and Dry Processes of a Cement Manufacturer? The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln ...
• Chalk is porous and often has high moisture content that leads it to its use in the ''semidry/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.
The cement industry is wonderful with the latest techniques, and using the dry methods and helping automatic systems, has witnessed tremendous advances in the 160 year history of manufacturing its own. Some of the cement production process like Alumina Cement, entirely is different from Production method of Portland cement.
The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln, whereas no water is added in the dry process.
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.

Wet process kilns. The original rotary cement kilns were called ''wet process'' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
