Manufacture of Portland Cement- Materials and Process
The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process
Cement - 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
