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 .
Jul 31, 2014· The stirred milling technology could further improve energy efficiency of cement grinding. Initial work indicates great potential and significant development in this direction should be expected. REFERENCES AND BIBLIOGRAPHY Austin, L. G., Weymont,, and Knobloch, O., 1980. The simulation of airswept cement mill.
Cement mill Wikipedia. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are .

Tight control of every step in production process is of outmost importance for achieving the maximum efficiency and quality of cement. From stock pile management, production of raw meal, preparation of kiln feed and the production of clinker right through to the final mixing of the end product the control is driven by the elemental, mineralogical composition and particle size analysis.

Globally, the cement sector is dominated by a small number of large companies. Largest cement companies, and their capacities and sales are also provided below. Cement production is an energy intensive process, with energy costs representing 2040% of production costs (IEA, 2007. p. 145).
Mill ventilation is important for cooling the mill, removing moisture and improving mill efficiency. Typically, a velocity across the media of 1m/s is a good target. The challenge is to measure it. Cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack.
