[email protected]cement raw mill is the primary piece of equipment used in the modern cement industry for the raw meal production process. As a result, it is critical to investigate the exergy efficiency in a cement raw mill in order to satisfy the need for the design and optimization of the cement plant manufacturing process.
Optimization, modernization and energy conservation projects are on the daily topic-list of every cement plant operation and management. However engineering is not the key-business of a cement plant and hence the resources, the judgement and the overview on technical developments are often limited. For

Abstract The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1 per annum. The electrical energy consumed in cement production is approximately 110 kWhtonne, and around 40 of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant ...
