An important benefit of enhancing energy efficiency in the cement industry would be the reduction in energy costs. Broadly speaking, in the EU cement industry the energy bill represents about 40% of total production costs, while European cement production techniques are amongst the most energy efficient in the world.
1. Introduction. Cement is an energyintensive industry in which the grinding circuits use more 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 ...
aspects, which, in the field of cement manufacturing, is synonymous with energy consumption savings. This has led, during the last two decades, to the emergence of innovative technologies in the field of grinding, aiming at reducing its electrical demand. The FCB Horomill® was developed and
The consumption of energy by the cement grinding operation amounts to one third of the total electrical energy used for the production of cement. The optimization of this process would yield substantial benefits in terms of energy savings and capacity increase. Optimization of the Cement .
