Cement manufacturing is the source of 5 of global CO2 emissions. 60 of emissions are due to the transformation of raw materials at high temperatures and 40 results from the combustion required to heat the cement kilns to 1500 C. Therefore emissions monitoring is extremely critical for cement plants to meet regulatory requirements.
Concrete manufacturers expect their raw material suppliers to supply a consistent, uniform product. At the cement production factory, the proportions of the various raw materials that go into cement must be checked to achieve a consistent kiln feed, and samples of the mix are frequently examined using X-ray fluorescence analysis.
Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
