Cement Plants: Coal
Coal is the fuel that undergoes least human intervention before use: it is burned in essentially the same condition in which it is dug from the ground. Because of this, the term "coal" has a breadth of meaning which reflects the variety of geological conditions under which the fuel is formed.
Energy Efficiency and Saving in the Cement Industry ...
Yet another way to reduce energy and process emissions in cement production is to blend cements with increased proportions of alternative (non-clinker) feedstocks, such as volcanic ash, granulated blast furnace slag from iron production, or fly ash from coal-fired power generation. The use of such blended cements varies widely from country to ...
What is the use of coal in the cement manufacturing industry ...
High grade coal has less ash and low grade coal has more ash. High ash coal is acceptable for captive power plants attached to Cement Plants because the fly ash generated can be used for making PPC Cement.
Alternative Fuels in Cement Manufacturing | IntechOpen

Cement Plants: Coke
Petcoke differs also in that it is tougher to grind, and there is a trend towards the use of more sophisticated fuel grinding circuits to cope with this. Despite these problems, cement kilns have been run on pure petcoke, and a 50:50 coal:petcoke mix is a fairly normal fuel mix nowadays.
Could Concrete Help Get Coal Ash Out of Neighborhoods ...
Coal ash is not required for making concrete, but according to Knowles, when it is added the resulting concrete is more stable, stronger and often less expensive to make than concrete made from limestone-based cement.

How Cement Is Made
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
Cement - Wikipedia
Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln (referred to as co-processing), replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications.
