5 ·The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing mainly limestone and clays A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km The limestone is excavated from open cast mines after drilling and blasting and loaded onto dumpers
·Cement Manufacturing Process Phase IV Kiln Phase Kiln is a huge rotating furnace also called as the heart of cement making process Here raw material is heated up to 1450 ⁰C This temperature begins a chemical reaction so called decarbonation In this reaction material like limestone releases the carbon dioxide
6 ·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 be dug directly by excavators
