Dry and wet process cement clinker grinding plant. 202074 process raw material grinding system (2).Dry process. PIC3 shows three processes a, b and c. Raw materials received by a plant contain a small amount of water. Limestone contains 2 to 5% of water and clay about 5 to 10%. The dry process needs to evaporate water when grinding.
Dry process. 1 Mixing of raw material in a dry state in blenders. 2 The dry materials exiting the mill are called kiln feed. 3 Size of the kiln needed for the manufacturing of cement is smaller. 4 Difficult to control mixing of Raw materials, so it is difficult to obtain a better homogeneous material.

manufacture of portland cement wet process and dry process ppt. And lime,The total consumption of coal in this method is only about kg when compared to the requirement of about kg for producing a ton of cement in the wet process the dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, silica and alumina .
Cement 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.
The process out clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by this process known as Portland cement. The cement manufacturing is done by majorly by two methods known as wet process and dry process depending on their mixing is done with water or without water.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
