Concept of utilizing solar energy for calcination reaction in the cement plant is shown in Fig. 2, inspired by earlier research (Gonzalez and Flamant, 2013). Design suggests a hybrid mode of operation for the plant. Sequence of raw material processing in a conventional cement plant involves preheating, pre-calcining, and clink erization.

Extraction and processing. 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 be dug directly by excavators.. The …

There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker. Grate cooler helps to cooler clinker, the cooled clinker is sent to the cement silo for storage.
