Excess inventory As clinker inventory levels have been building up in the kingdom, the need to export has significantly increased. Al Rajhi Capital estimates that inventories stood at 35.2Mt in February 2018, or 75 per cent of domestic sales in the last 12 months. January saw the first decline in inventories, by-1.3 per cent, since April 2017 and clinker production was down by 25 per cent YoY ...

Reactions in the cement kiln - clinkering

Clinker: reactions in the kiln. The milled and blended raw materials go to a silo and then to the kiln. Reactions which take place as the feed passes through the kiln are reviewed below. They can be considered under three broad headings: Decomposition of raw materials - temperatures up to about 1300 °C. Alite formation and other reactions at 1300 C-1450 °C in the burning zone. Cooling of the ...

New low-carbon cement | World Cement

As Karen Scrivener, the principle investigator of the project, explains, the strength of the combination of calcined clay and ground limestone, which the researchers call LC3 for Limestone Calcined clay Clinker Cement, lies in its chemistry. When used together, the aluminates from the calcined clay interact with the calcium carbonates from the limestone, leading to a less porous, and therefore ...

Calcination - Wikipedia

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 → CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 °C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.
