Cement clinker is grinding in roller mills and ball mills, for example, along with granulated blast furnace slag, fly ash, limestone, and approximately 5% sulfate agents (e.g. gypsum). During production and before leaving the plant, the cement is internally inspected and tested in the plant's laboratories.

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) Direct firing and b) Indirect firing. In direct firing system, coal is milled on line and is directly fed to the kiln. The

A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill); heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). What kind of coal is used in cement plants? Lignite.

Coal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. The grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. If the limestone used in the cement manufacturing process is of high grade then low-grade coal is used and vice versa.

In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.

On a coal-fired works, the composition of the coal ash also needs to be allowed for, since the ash falls onto the part-reacted feed and combines with it. In practice, a works may have 5 or 6 raw materials in order to control composition. Alite is the clinker mineral that contributes most to strength in concrete, especially earlier strengths.

The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials.
