2 CEMENT MANUFACTURING PROCESS A cement production plant consists of three major processes such as quarry and raw material preparation, clinker production and cement grinding and distribution [2]. During raw material preparation first, limestone and other raw materials are extracted using drilling and blasting techniques.
Quarrying is the process of extracting rocks and other materials from the ground for use in the production of cement. These materials can include limestone, clay, sand, iron ore, and other minerals.
Step 1: Mining. 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 ...
