The heating process in the cement kiln requires intense energy to heat the clinker and compensate for the heating loss. Studies illustrate a significant loss of energy (> 50 %) in cement kilns, as shown in Fig. 2 [4].Thus, there is a need for optimal design and efficient operation of the cement kiln to minimise this energy loss.

Cement - Extraction, Processing, Manufacturing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can …
