Generic Concrete Products with Portland Cement

 &#; Portland cement is manufactured using one of four processes: wet, long dry, preheater, or precalciner. The wet process is the oldest and uses the most energy due to the energy required to evaporate the water. New cement manufacturing plants are being constructed, and older plants converted, to use the more energy efficient

Cement Manufacturing Process: What is Cement …

 &#; 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.

Cement Production

 &#; In the wet process, the feedstock is ground and blended in the form of slurry. Removal of this excess water necessitates the use of a longer kiln for the wet process. The total power consumption in this process is also higher and the output lower than in the dry process. However, blending is much easier in a wet state.
