The cement manufacturing process starts from the mining of limestone, which is the main raw material for making cement. Limestone is excavated from open cast mines after drilling and blasting and loaded on to dumpers which transport the material and unload into hoppers of the limestone crushers.

Industrial Raw Quicklime Mineral also known as calcium oxide CaO is a term commonly applied to several related materials. Pure lime is calcium oxide CaO formed by “burning” a form of calcium carbonate such as limestone or marble CaCO 3. Calcium oxide is a key ingredient for the process of making cement. As a cheap and widely available alkali.

More than 50 percent of the emissions from cement production are intrinsically linked to the production of clinker and are a by-product of the chemical reaction that drives the current process. There is potential to blend clinker with alternative materials to reduce the need for clinker itself and thus help reduce the climate impacts of the cement-making process.

There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

Cement manufacturing process in summary. Portland cement is manufactured by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.
