Limestone, shells and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand and iron ore are used to make the cement. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw

Cements makes up between 10% to 15% of concrete’s total mass; though of course the exact proportions may vary from one mixture to the next, depending on the type of concrete is being made. To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln.

Cement is manufactured by heating a precise mixture of finely ground limestone, clay and sand in a rotating kiln to temperatures reaching 1450ºC. This results in the production of cement clinker, an intermediate product in the manufacture of cement. The cement clinker emerges from the kiln, is cooled, and then finely ground to produce the powder we know as cement. The fuels combusted to heat

Apart from limestone, there are also other raw materials used in the cement making process, such as clay, fly ash, iron ore, and coal. The need for these raw materials in cement production is relatively small so it is OK to just buy them from a supplier.

2018-3-3 · The process followed for making cement is first limestone and clay are crushed and are mixed in a mixer to properly combine them together, after that the mixture is then heated in a rotating heater once this process is completed the final step is grinding and then finally cement is ready to use.

This cement is made 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, which then chemically combines with the other materials in the mix to form calcium silicates and other cementitious

Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements
