Manufacturing process Lafarge in South Africa Cement 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.Use of Cement Hydration Stabilizer Admixture at Ready Mix Concrete from ready mix plant is the main raw material consumed in construction industry. A significant waste quantity is generated with fresh concrete returned to the production center due to their inadequate alloion or demand preview. To minimize the amount of this material wasted, misused, discarded, could be used the Hydration Stabilizer Admixture (HSA).

At which temperature cement is manufactured? QuoraCLINKER is the basic material for making cement and raw meal consisting of lime stone, iron ore, bauxite and silica [all in powder form of suitable fineness] will be passing through various cyclones in preheater and hot air will be pumped from bottom to top and thus this mixture is preheated and this will be passing through rotary kiln wherein coal powder will be injected and fired at aSchwenk KG BEUMER GroupTo obtain Portland cement clinker, a coarse intermediate product, the raw meal is first transported into the cyclone preheater, then into the calcinator, both powered by alternative fuels. The limestone portion of the raw meal is deacidified at temperatures of over 950 degrees Celsius.

For instance, CO 2 emissions during transport could be reduced by replacing diesel fuel with biodiesel. Normally, energy efficiency improvements proportionally reduce the emissions of CO 2 generated from fossil fuel

Dry process kilns. In a modern works, the blended raw material enters the kiln via the preheater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the
