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.
Wet Polishing. Polishing concrete wet may be the older way of doing it, but it has enjoyed a small resurgence lately. Most of wet polishing's benefits stand out in contrast to the downfalls of dry polishing. Keeping things wet reduces the amount of silica that is released into the air, making it a safer area for breathing.
Types of ordinary portland cement: There are two methods for manufacturing of cement as follow: Wet manufacturing process: In this method, mixing and grinding of raw materials is done in a wet state.
