Working of cement kiln

Apr 23, 2021 Introduction of Cement Kiln Working Zone. 2021-04-23. According to the temperature of the materials in the kiln, the cement rotary kiln system can be divided into: drying zone, preheating zone, decomposition zone, exothermic reaction zone, burning zone and cooling zone. The drying zone is a short part at the raw material entrance

    Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C
