7.0 The industry would be using "wet" method for the production of clinker their process. in In the wet method, water is added to the raw materials after milling to promote thorough mixing, and the mixture is added to the kiln as slurry, containing 30-40% water. The different process steps involved in the production of cement are;

Alternative Fuel Use in Cement Manufacturing

production: improving energy efficiency throughout the process, reducing the clinker content of cement with mineral substitutes, and replacing coal and petcoke with lower-carbon alternative fuels. As will be shown in the following sections, the cement industry has already pursued improvements in energy efficiency and reductions in clinker content.

Clinkerization - Cement Plant Optimization

The overall process of conversion from raw meal to clinker being endothermic demands a theoretical heat of about 380-420 kcal/kg-clinker. However, the rest of the specific heat consumption as tabulated above constitutes heat losses from preheater exhaust gases, clinker, cooler exhaust gases, preheater dust and radiation losses.

Chemical exergy influence in the exergetic analysis of a ...

The most energy demanding process in the cement industry is clinker production, carried out in a rotary kiln. Thus, rotary kiln energetic and exergetic analyses are useful tools to reach cement production process improvements. Energetic analysis is based on the first law of thermodynamics and allows one to calculate the heat uses and losses. On the other hand, …
