The document describes the process of cement production using the wet process method. It involves mixing raw materials like limestone and clay into a slurry with 32-36% water. This slurry is then fed into a cement kiln where it is dried and calcined at 1400-1500°C to form clinker. The clinker is then cooled, ground, and gypsum is added to produce the final cement product. …

Stage 4: Burning . The raw mix is pre-heated before it goes to the kiln, which is heated by a flame that can be as hot as 2000° C.; The raw mix burns at 1500° C producing Clinker.; Stage 5: Grinding . The Clinker and the Gypsum are very finely ground giving pure Cement. Other secondary additives and material can also be added to make a blended cement.

The raw material processing operations differ somewhat for wet and dry processes, as described in the paragraphs below. Cement raw materials are received with an initial moisture content varying from 1 to more than 50 percent. If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding.
