The cost of energy is 50-70% of the total cost of cement production in Egypt. The cement industry is one of the energy-intensive sectors in Germany, with an energy input of around 30 TWh per annum (fuels + electricity) and energy costs amounting to more than 30% of gross value added. The total energy evaluation was based on the Modern dry-process cement plants with an efficient grinding and pyro processing system, typically consume less than 700 kcal/kg-cl of thermal energy and 100 kWh/mt of electrical energy. This figure is much lower than cement consumption in its peers Malaysia (over 600 kilogram per capita) or Vietnam. Steppe Cement holds a 15% market share. The demand for cement is strongly correlated to the rate of economic development. Carbon dioxide emissions from the production of concrete stem from two primary sources: the energy used in the production of cement and the chemical process of calcining limestone into cement (CaCO3 -> CaO + CO2). Alimuzzaman,PMP na LinkedIn: #INfluenCement #cement #technology To give a more detailed look at energy consumption within cement manufacturing, four sub-processes are explored throughout this reportcrushing/grinding, pyroprocessing with cooling, finish grinding, and storage. 2.
