Wet Process and Dry Process Wet Process. The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker.
MoreAug 21, 2019 The wet process of cement manufacturing too popular for several decades because of the possibility of more accurate control while raw material mixing. After that, the dry process of raw material mixing gained momentum with the modem development of the technique of dry mixing of powdered materials using compressed air.

MoreMethods 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.
