Oct 23 2015 Cement is an energyintensive industry in which the grinding circuits use than 60 of the total electrical energy consumed and account for most of the manufacturing cost The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns In recent years the production of composite cements has been.
The cement industry has remarked as an intensive consumer of energy The amount of energy consumed in the cement manufacturing has a correlation to the increasing of CO2 emission It is reported that the cement Industry has contributed to 57 of the total CO2 emission in the world Thus there is a need to make an innovation in order to overcome the environmental problem.
The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement The powdered cement is then mixed with water and aggregates to form concrete that is used in construction Clinker quality depends on raw material composition which has to be closely monitored to ensure the quality of the cement Excess free lime.
