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.
Use of fuels with higher hydrogen content than coal and use of alternative fuels can reduce net greenhouse gas emissions. Dust. To manufacture 1 t of Portland cement, about 1.5 to 1.7 t raw materials, 0.1 t coal and 1 t clinker (besides other cement constituents and sulfate agents) must be ground to dust fineness during production. In this ...
The normal "green" coke is used as a fuel, where it can be more convenient to use than fuel oil because its properties are sufficiently similar to those of coal that coal/petcoke mixtures can be used in power generation or cement manufacture in whatever proportions desired without major modifications to plant.
The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal 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) …

Fly ash has been successfully used as a mineral admixture in PCC for nearly 60 years. This is the largest single use of fly ash. It can also be used as a feed material for producing Portland cement and as a component of a Portland-pozzolan blended cement. Fly ash must be in a dry form when used as a mineral admixture.
Concrete is the second most consumed substance on Earth after water. On average, each year, three tons of concrete are consumed by every person on the planet. Concrete is used globally to build buildings, bridges, roads, runways, sidewalks, and dams. Cement is indispensable for construction activity, so it is tightly linked to the global economy.
This coal type is mostly used for power generation, cement manufacturing and other industrial purposes, while metallurgical coal is used primarily for manufacturing iron and steel. Anthracite is the most mature coal and thus has the highest carbon content of any type of coal.
in the cement industry, in cases where the raw material chemical composition varies greatly. Prehomogenisation is used primarily for the main components in cement production, i.e. limestone and clay. With the increasing variation in the grades of coal used for coal firing installations, there is a growing need for prehomogenisation and storage of
