Study on environmental load and the control approach in cement industry

The consumption of material source and energy source and the emission of pollutant etc.in cement production process is an important problem about cement industry sustainable development. Aiming at these problem, macro analysis and research are carried out and the technology of producting low-environmental-load and high-performance cement is discussed. The research shows that the most effect factor of cement industry to environmental load is enery source and material source such as fuel,power and limestone etc. and emission of dust,CO2, SO2,and NOx and the noise pollution. In condition of precalciner kiln technology, to realize low-environmental-load clinker and to solve environmental load problem of China cement industry, it can be discussed by aspects as optimize proportion to utilization industry waste mostly, develop high-efficency burner and high-activity functional cementing material and high-benefit low-energy-consumption grinding system etc.
