Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
Manufacturing of cement is a very critical process because there are more than 25 types of cement. It begins with mining, grinding of material, and then passes through the kiln at 1450° C which is very high temperature and then gypsum is added with it.
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.
All of these stages are covered in the article What You Need to Know about Portland Cement Manufacturing Process we mentioned before. Similar to the dry process, materials also need to undergo quarrying, primary crushing, secondary crushing, proportioning and grinding in the raw materials preparation stage of the wet process.
