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.

They are used to grind down the concrete surface to achieve the desired degree of smoothness and shiny texture in the concrete. Like the process of sanding wood, when the grinder moves on the concrete surface, it produces fine particles of concrete dust due to grinding. After removing the concrete dust, a fine mirror-like glossy finish is obtained.

Dry process The raw materials are crushed and fed in the correct proportions into a grinding mill, where they are dried and reduced in size to a fine powder. The dry powder, called raw meal, is then pumped to a blending silo, and final adjustment is now made in the proportions of the materials required for the manufacture of cement.
