According to the CSI'·s "Getting the Numbers Right" (World Business Council for Sustainable Development, 2009), the dry manufacturing process with preheaters and pre-calciner technology, used in a large number of cement production plants globally, had an average specific energy consumption of 3,605 MJ/t clinker in 1990 but saw a ...
The next step in the production process is the creation of clinker, which is the most energy and emissions intensive step in the cement production process. In clinker production the mixture of raw ...
Subsequently, clinker is grinded and combined with other components, such as calcium sulfate or pozzuolan, obtaining the desired type of cement. The clinker production phase at issue processes about 899000 tons per year of raw meal, using 59100 tons per year of fuel (coal); about 584000 tons per year of clinker are produced.
The powdery or granular mixture quickly solidifies into spherical nodules of clinker. Cooling and storing. The mixture inside the slightly inclined kiln is rapidly cooled from 2000°C to 100°C-200°C. Thus, the final product, clinker, is produced, and then stored, ready for the production of cement.
Global cement production has reached 3.9 billion tons. However, the clinkerization process, which is the basis of cement production, is responsible for an approximate annual global CO2 emission of 2 billion …

Clinker is produced by fusing together limestone, clay, and other materials in a rotary kiln at temperatures nearing 1500°C. Fossil fuels are typically used to heat the …
The heat required for the pyro-processing (clinker production phase) is obtained primarily by combusting fossil fuels (mainly, coal) (Ige et al., 2022). Efforts are underway to decrease the dependence on fossil fuels in clinker production phase by co-firing alternative fuels (AFs) such as biomass and RDF (World Bank, 2017). In a typical modern ...
NSP rotary kilns started to account for more than 10% of the market share in 2001, and China's national cement production peaked in 2014. Therefore, 2001 and 2014 are selected as typical years ...
The clinker is then cooled, ground and blended with other materials to make cement. The combustion of fuels to heat cement kilns is responsible for 35% of clinker's carbon footprint. The other 65% are process emissions, released during the calcination reaction involved in the production of clinker. Headlines
Cement kiln is the main equipment for clinker sintering. From structure, it can be divided into rotary cement kiln and shaft kiln, while, from the working principle, it can be divided into the dry method and wet method kiln. …

The process also consumes up to three percent of the global energy supply. After the oil crisis in the early 1970s, cement manufacturers have been seeking out better ways to cut production costs by using alternative fuels. Five decades later, the industry is inundated with unprecedented knowledge about various processes and vital data on ...
The cement production process is one of the most energy-consuming processes and has a strong environmental impact. The main impact on the energy consumption of cement production is the burning process of cement clinker in a rotary kiln, and the energy costs associated with burning cement clinker constitute 50-75% of cement production costs.
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish in color, which is produced by sintering limestone and alumino-silicate materials such as clay at high temperatures in a cement kiln.
CO 2 emissions are directly proportionate to the amount of clinker used in cement production. Therefore, clinker can be substituted by cementitious materials such as natural and calcined pozzolans, as well as industrial byproducts such as fly ash and blast furnace slag. Similarly, the use of pozzolans depends on their availability, as natural ...
