Atmaca, A. & Kanoglu, M. Reducing energy consumption of a raw mill in cement industry. Energy 42, 261–269 (2012). Article Google ScholarThe essentials of electrical systems in cement plants EEP,Average kWh/ton of material ground = 2608/150 = 174 kWh. Power consumption per ton of clinker with a conversion ratio for consumption 1.55 : 1 = 17.4 x 1.55 = 27 kWh/ton. Using 4% gypsum 1 ton clinker = 1.04 tons of cement. Therefore power consumption per ton of cement = ~26.0 kWh.Reducing energy consumption of a raw mill in cement ,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.
Martin and McGarel proposed a methodology about the process control and management in raw mills and cement mills in cement industry to decrease the SEC for cement by 3–3.5 kWh/ton of cement. A rotary burner with a daily production capacity of 600ton clinker has been studied by Engin and Ari .

Slag Mill is widely used in various manufacture industries, like cement, silicate, new building material, dry and wet grinding for all kinds of ores and other materials. Application : Cement Plant, Clinker Grinding Unit, Quicklime Plant Capacity : 1178 t/h Power consumption : 50~80 kWh/t Motor Power : 954500 kW Fineness : 38004000 cm²/gEnergy and Economic Comparison of Different Fuels in ,Cement clinkerisation is the major energyconsuming process in cement manufacturing due to the hightemperature requirement. In this paper, energy data including specific energy consumption, forms, and types of energy used at different units of cement manufacturing processes were analyzed and compared for effectiveness, availability, CARBON DIOXIDE EMISSIONS FROM THE GLOBAL ,Energy consumption by the cement industry is estimated at about 2% of the global primary energy consumption, or almost 5% of the total global industrial energy consumption . Because of the dominant use of carbonintensive fuels, such as coal in clinker making, the cement industry is a major source of CO 2 emissions.
