manufacture of portland cement wet process and dry process pptCement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
Manufacturing the cement kiln Understanding CementTypically, 30%40% of the meal is decarbonated before entering the kiln. A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner.

Cement Production The Concrete PortalThe feedstock is interground and blended in a dry form. For MC between 8 and 15 %, a raw meal slurry (similar to wet process) is prepared, sent through a short kiln with a cyclonic preheater. 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 Manufacture of Portland Cementconstituents of Portland cement. The powder from the dry process doesn't contain much moisture, so can be dried in a preheater tower. As it falls through the tower (which takes 30 seconds) it is heated from 70 to 800oC. The moisture evaporates, up to 20% of the decarbonation (loss of CO 2) occurs and some intermediate phases such as CaO•Al
