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
Cement manufacturing is a complex and energyintensive process A key stage in this process is the conversion of ground raw materials CaCO 3 clay and or shale into clinker synthetic cementitious minerals in the kiln A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln Further
In cement manufacturing conditions favorable for formation of nitrogen oxides NO x are reached routinely because of high process temperatures Essentially all NO x emissions associated with cement manufacturing are generated in cement kilns In cement kilns NO x emissions are formed during fuel combustion by two primary mechanisms
