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 which transport the materials and unload into hoppers ...

The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.

Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further
