There are two different processes for manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder-like substance. Both the processes are in use and have their own advantages and disadvantages.
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 flow-ability characteristics. 3. Size of the kiln needed for manufacturing of cement is bigger. 4. Raw material ca...
28-3-2018· Wet process Mixing of Raw materials in wash mill with 35 to 50% water. Materials exiting the mill are called "slurry" and have flow-ability characteristics. Size of the kiln needed for manufacturing of cement is bigger. Raw material can be mixed easily, so a better homogeneous material can be obtained Fuel consumption is high i.e.,
Dry Process for Manufacturing of Cement. In semi-dry process, the blended meal is now sieved and fed into a rotating dish called a granulator, of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.
30-12-2019· Other articles where Wet process is discussed: 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
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.
31-7-2013· Wet process. Dry process. Now let us discuss wet process and dry process detailed.WET PROCESS:In the wet process, first the clay is purified by washing in a wash mill.The lime stone is crushed into small particles and mixed with purified clay in proper proportions to get raw slurry.DRY PROCESS: In the dry process

Difference between dry process and wet process of cement production. Dry process. Wet process. Raw materials are mixed in its dry state. Raw materials are mixed in wash mill along with 30-50% of water. Dry mixed raw materials entering to the kiln are called as kiln feed.
If we consider the Quality and Rate then wet process is better and if we consider Fuel consumption and Time of Process then dry process is better. * Dry Process The both calcareous and argillaceous raw materials are firstly crushed in the gyratory...
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.
3-1-2020· Other articles where Dry process is discussed: cement: Manufacture of cement: 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 the
Process Discretion: Wet process, Semi-dry process, Dry process and Finish process. The environmental im pact of the cement production and its variations between different cement plants, using Life C ycle Impact assessment .
24-8-2018· Dry process These are two different processes of manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substance.Both the processes are in use and have their own advantages and disadvantages.While in wet process grinding is
Comparison between wet and dry process Wet process Dry process 1- Moisture content of the slurry is 35-50% 1- Moisture content of the pellets is 12% 2- Size of the kiln needed to manufacture the cement is bigger 2- Size of the kiln needed to manufacture the cement is smaller 3- The amount of heat required is higher, so the required fuel
Furthermore, a larger kiln was needed for a given clinker output, because much of the kiln's length was used up for the drying process. On the other hand, the wet process had a number of advantages. Wet grinding of hard minerals is usually much more efficient than dry grinding.
The plant adopted for the study has a wet production capacity of 1 million tonnes per year and a dry process output of 1.2 million tonnes per year. Six operation units are identified for the wet process while five units are identified for the dry process. The operation units con- sidered for the purpose of this work include crushing,
22-9-2018· Dry mix process and wet mix process are the two methods of shotcrete construction which are based on the time at which the water is added to the mortar or Shotcrete is a type of concrete or mortar mix that is shot onto a surface at high-speed. The shotcrete process can be performed in two ways, either using a dry mix or by means of a
cement manufacture dry and wet processes jillscityspa. Wet Process Cement Manufacturing,,Dry, semi-dry, semi-wet and wet processes are the four main process routes that are used for the production of cement. Live Chat; wet and dry process of making cement cgimathuraorg.
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 stateand, In the wet process, however, these materials are supplied into the kiln in the form of an intimate mixture with water called SLURRY. 1. Dry

The process is accordingly known as the dry process or the wet process of mixing. Dry process (modern technology) In this process, the raw materials are first reduced in size of about 25mm in crushers. A current of dry air is then passed over these dried materials. These materials are then pulverized into fine powder in ball mills and tube mills.
Later, the dry process gained momentum with modern development of technique’s 5. Wet process • Wet process : In this process, the raw materials are changed to powdered form in the presence of water . In this process, raw materials are pulverized by using a Ball mill, which is a rotary steel cylinder with hardened steel balls.
