Cement consumption is dependent on the time of year and prevalent weather conditions. Nearly twothirds of cement consumption occurs in the six months between May and October. The seasonal nature of the industry can result in large swings in cement and clinker (unfinished raw material) inventories at cement plants over the course of a year.
The use of other constituents in cement and the reduction of the clinkertocement ratio means lower emissions and lower energy use. Ordinary Portland cement can contain up to 95% clinker (the other 5% being gypsum). The current average clinkertocement ratio over all cement .
Today, electrical energy consumption in cement works makes up over 10 per cent ... made to the energy efficiency of rotary kiln plants in German cement works. After the reunification of Germany, construction and modernisation of works in ... 35 per cent of the total requirement), the burning and cooling of the clinker (approx.

SICEMENT – solutions for the next level of productivity Companies in the global cement industry are facing major challenges: If they are to improve productivity while simultaneously decreasing costs, they need highperformance products that are also energyefficient and offer maximum availability and flexibility.
Clinker grinding: Energy efficiency in clinker production, Clinker Grinding and Storage for Cement Production After gypsum and additives have been added, final grinding for cement production can take place in the cement plant The Siemens control system gives you everything you need to benefit from maximum transparency for clinker storage and grinding
This concept is used in producing a type of clinker with up to 30% less carbon dioxide emission. Energy efficiency improves and the electricity costs for the manufacturing process are about 15% lower as well. Use of Clinker: Conversion to Cement. Clinker, combined with additives and ground into a fine powder, is used as a binder in cement products.
The use of SCMs reduces the quantity of clinker or cement required. They are added to cement either at the grinding stage or by blending with cement after grinding; or can be added during concrete batching to supplement the cement. Because of differences in chemistry, SCMs affect the performance of cement in concrete to suit different applications.
Back in the 1950s and 1960s, considerable improvements were made to the energy efficiency of rotary kiln plants in German cement works. After the reunification of Germany, construction and modernisation of works in eastern Germany led to a further reduction in specific energy consumption.

When it comes to achieving the best energy consumption, what are the key factors a cement producer needs to address? In this article, extracted from the newly published Cement Plant Environmental Handbook (Second Edition), Lawrie Evans presents a masterclass in understanding and optimising cement plant energy consumption.
G. Habert, in Ecoefficient Construction and Building Materials, 2014. Energy efficiency. Energy demand in clinker production has been significantly reduced over the last few decades. The theoretical minimum primary energy consumption (heat) for the chemical and mineralogical reactions is approximately – GJ/t (Klein and Hoening, 2006).However, there are technical reasons why this .
Thermal efficiency. Cement kilns have become highly energy efficient as older plants are being upgraded or energy intensity of cement manufacturing is influenced by regional characteristics such as raw material moisture content and burnability, fuel types, plant size distribution, and cement standards.

Key strategies to cut carbon emissions in cement production include improving energy efficiency, switching to lowercarbon fuels, reducing the clinkertocement ratio and advancing process and technology innovations. The latter two contribute the most to direct emissions reductions in the Sustainable Development Scenario (SDS).
