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.
Feb 07, 2019 Feb 07, 2019 The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness. That is why high quality grinding balls with high hardness over the entire section are used during grinding materials in tube mills in this industry.
The grinding process consumes the most energy in the cement production, its energy consumption accounts for more than 70 of the total power consumption in the whole process of cement production. There are three main grinding processes in the cement production raw meal grinding, cement grinding, and raw coal grinding.
industry has increased the demand of cement. Increase of the cement utilization demands for higher production efficiency and ultimately low production cost. The efficiency of the cement production depends greatly upon the efficiency of a grinding mill which consumes 60-70 of the total electricity consumption of the cement plant12.
