  • Reducing energy consumption of a raw mill in cement industry

    In this study the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be 61.5 and 16.4 respectively. Finally the limestone is extracted transversely from the stockpile by the reclaimer and conveyed to a raw mill bin for grinding. Step 3. The raw mix goes into the raw mills for drying and fine grinding then comes out as raw meal. The raw meal is then stored and homogenised in a concrete silo.
