(ii) wet process (old technology): in the earlier part of the century i.e., from 1913 to 1960, the wet process was used for the manufacture of cement. from 1913 onwards, the cement industry underwent a number of changes mainly to suit the requirements of.
All about the wet process of cement manufacturing wet process and dry process. the wet process of cement manufacturing refers to grinding raw material into slurry after procedures of the wet process. the procedures of the wet process are basically the same with the dry process, which can.
Although the dry process is the most modern and popular way to manufacture cement, some kilns in the united states use a wet process. the two processes are essentially alike except in the wet process, the raw materials are ground with water before being fed into the kiln.
Wet process ( old technology ) in the earlier part of the century i.e., from 1913 to 1960, the wet process was used for the manufacture of cement. from 1913 onwards, the cement industry underwent a number of changes mainly to suit the requirements of the manufactures and the govt. policies till early 1982.

In cement: manufacture of cement. manufacture are known as the wet, dry, and semidry processes and are so termed when the raw materials are ground wet and fed to the kiln as a slurry, ground dry and fed as a dry powder, or ground dry and then moistened to form nodules that are fed to. read more.
Here is the manufacturing of cement by wet process. wet process. when the raw materials are soft, then the wet process is preferable to be used. the cement is manufactured by the following procedure:mixing of raw materials: in the wet process, there are two raw materials e. calcareous and argillaceous.
The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. the larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. the manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.
Manufacture process of cement . 1) mixing of raw material:a materials like as limestone or chalk and shale or clay may be mixed either in dry condition or wet process of according is known as dry process or wet process of mixing. a) dry process: a dry process, the raw materials are first reduced in size of 25mm in current of dry air is then passed over the dried.

Note. to produce one tone of cement, 100 kg coal is used. all cement plants after 1980s use the dry process for manufacture of cement. in wet process to make one tone of cement, 350 kg of coal is used. burning amp; grinding process remains same for both dry amp; wet process.
Mixing of raw materials: the processes used for the manufacture of portland cement can be classified as dry and wet. in dry process. the raw materials are first reduced in size of about 25mm in crushers and crushed material is ground to get fine particles into ball mill or tube mill. each material after screening is stored in a separate hopper.
Manufacturing of cement. by any one of the two methods : (i) dry process, and (ii) wet process. in both these processes the three distinct operations of (a) mixing, ball mill (b) burning, rotary kiln and (c) grinding are carried out. 1. dry process.

The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln, whereas no water is added in the dry process.
Types of , manufacture of cement – consists of mixing, burning, and grinding processes 1 mixing: it may be a wet process or by dry processin a wet process wash mill is used which is a heavy cylinder of 25 to 30 m in diameter and 9 to 12 m in length it is kept slightly inclined to the horizontal and can rotate at 15–20 revolutions per minute.

Wet process kilns. the original rotary cement kilns were called 'wet process' kilns. in their basic form they were relatively simple compared with modern developments. the raw meal was supplied at ambient temperature in the form of a slurry. a wet process kiln may be up to 200m long and 6m in diameter.
Wet process. 1 mixing of raw materials in wash mill with 35 to 50 water. 2 materials exiting the mill are called slurry and have flowability characteristics. 3 size of the kiln needed for the manufacturing of cement is bigger. 4 raw material can be mixed easily, so.
Wet process. the specific feature of the wet process is that the raw materials are prepared in water whereas in the dry process the materials are ground and mixed dry. the flowsheet diagram of the wet process for manufacturing portland cement is given in figure 3.3. the limestone is.
