what type of coal is used to make cement

Coal in the cement industry

plays an important role in the manufacturing process of cement. Based on the composition of raw feed a wide range of coal is used. In a cement plant two systems of coal firing are used, namely, a) Direct firing and b) Indirect firing. In direct firing system, coal is milled on line and is directly fed to the kiln. The

Which type of coal use by cement industry.

Bituminous coals make the best coke and are in any case the most common, and these are most often used in the cement industry, although steam coals are occasionally used. When burning a pulverised fuel, higher volatiles are preferred because they speed up ignition and allow a coarser grind to be used.

What is the use of coal in the cement

Coal is used to burn raw material to clinkering temp. i.e 1450 degree centigrade. Low grade coal can be used for cement manufacturing but it will need high grade of limestone for good quality cement. you can say low grade coal need high grade limestone and high grade coal need low grade limestone. 5.6K views

RAW MATERIALS IN CEMENT PRODUCTION -

Carbonate and clay components are used to provide the necessary content of CaCO3. They have different carbonate components of CaCO 3 (titer). The carbonate component contains up to 97% CaCO3, clay contains about 10%. It is necessary to achieve, for example, a titer of 80%.

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind only water as ...
