The energy use for cement production is distributed as follows: % for pyroprocessing % for finishing grinding and % for raw grinding (Choate, 2003). The choice of fuel use entails the level at which green house gases (GHG) are emitted, the cost of cement and the quality of the cement produced. This research work will help in selecting the best fuel and

Cementlock™ is an environmental turnkey manufacturing process that disassociates and/or destroys the toxic properties of contaminants in sediments and soils, industrial wastes, etc. from years of environmental degradation. the sediments/soil are melted into a cement product called ecomelt which is nonhazardous and stable, and used as a 40% replacement for portland cement in concrete for
The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energyintensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 a decline of 89 percent while the number of dry process kilns has only

· Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide. High temperature of kiln

Building Materials Equipment Destroy for cement production Building materials equipment mainly includes cement production equipment, activated lime production equipment, etc., standardized production processes to ensure the smooth operation of equipment and processes, and ensure the interests of customers.
· The cement manufacturing industry is also under increasing pressure to reduce emissions. Cement manufacturing releases a lot of emissions such as carbon dioxide (CO 2) and nitrogen oxide (NO x). It is estimated that 5 percent of global carbon dioxide emissions originate from cement production (Hendriks, et al, 1998).

· Cement production is an energyintensive process consuming thermal energy of the order of GJ/tonne of clinker produced, which accounts for 30 – 40 percent of production costs (Giddings et al., 2000; EC, 2001). Worldwide, coal is the predominant fuel burned in cement kilns. Cement production consumes approximately 120 kg of coal per tonne of cement. In the European Union

Cement production is a thermal energy intensive process, which requires heating solid particles up to 1450°C and cooling it down. The process generates hot and CO 2 rich exhaust streams. Fin order to study energy efficiency of the process, authors like Mujumdar et al. (2006, 2007) developed detail models of process units, while others highlighted energy and exergy
