Subsequently, clinker is grinded and combined with other components, such as calcium sulfate or pozzuolan, obtaining the desired type of cement. The clinker production phase at issue processes about 899000 tons per year of raw meal, using 59100 tons per year of fuel (coal); about 584000 tons per year of clinker are produced.
In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
Additionally, the presence of alkalis can lead to the formation of free lime (i.e., uncombined lime) in the clinker (Figure 2, chemical equations 6 and 7), affecting the quality of the clinker and producing cement that has low compressive strength and higher expansion (Chatterjee and Sui Citation 2019). Using alternative fuels such as polyvinyl ...

Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.
