    Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.Cement plants are generally located adjacent to raw material quarries to minimize transportation costs (BGS, 2014 van Oss Padovani, 2002).

    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 excavated materials are transported to the crushing.Raw Materials. The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel.

    Aug 30, 2012 Cement Manufacturing Process Phase 1 Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand clay fulfill the need of silicon, iron and aluminum.Cement has excellent binding property but its production requires large amount of energy which contributes for pollution and global warming. The process of cement production starts from mining for raw materials, crushing, blending and heating these materials at high temperature of 1500 0 C and finally creating cement from heated materials All the process involved in manufacturing of cement.
