Cement is a crucial building material used in construction. The Cement manufacturing process involves the extraction and preparation of raw materials, such as Limestone, clay, shale, iron ore, and Gypsum. These materials are crushed, ground, and blended to form a raw meal, which is then heated in a kiln at high temperatures.
Mixing and Crushing: b) Wet Process • Limestone is crushed, powdered and stored in silos • Clay is washed with water to remove organic matter and stored in basin • Both these materials are mixed in grinding mill to form slurry • Slurry contains 38-40% water stored in correcting basin Figure showing manufacturing of cement using wet process.
Dry Process and Wet Process. Dry Process: The both calcareous and argillaceous raw materials are firstly crushed in the gyratory crushers to get 2-5cm size pieces separately. The crushed materials are again grinded to get fine particles into ball or tube mill. After screening this finely grinded materials are stored in hopper.
Wet process of cement production The raw materials are ground into raw slurry by adding water and powder, and then fed into the wet kiln to calcine the …
Wet process cement is a method of manufacturing cement that involves the use of water and a slurry of raw materials to create a cement paste that can be formed into a mold and allowed to harden.

The kiln must work continuously to ensure a steady regime and uniformity of the clinker. A conventional, larger kiln in a wet process plant produces 3600 tons of clinker per day. Cement manufacturing by wet the process is energy-intensive, so it is uneconomical compared to dry process and semi-dry process.
Cement Manufacturing Process Simplified Flow Chart. Cement manufacturing process - components of a cement plant from quarry to kiln to cement mill.
In general, a full cement production process includes the stone crushing, raw mill process, clinker process, and cement grinding process, cement packing process, and related process. The Portland cement manufacturing process is representative of all types of cement. limestone and clay are the main raw materials of …

1. Convert the following flow chart into a paragraph of about 150 words. The process of making cement is described in this flow chart. The two raw materials used in theprocess are limestone and clay. Limestone is crushed, sized, dried and stored in storage silos. In the same way, Clay is washed, crushed, and dried in storage basins.
The paragraphs below briefly describe the process, starting with the wet process and then noting differences in the other processes. In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1.
Cement manufacturing by wet the process is energy-intensive, so it is uneconomical compared to dry process and semi-dry process. ALSO READ: DETAILED …
Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement.

Generally, the proportion of components in cement raw materials is 67-75% limestone, 10-15% clay, 0.5-1.5% iron ore and 8.5-11% coal. The laboratory of a cement plant. With the help of vertical roller mills or other types of crushers, the raw materials are blended and further ground into smaller pieces of raw meal in the cement plant.
Cement is manufactured using an earlier, less popular method called wet production. In the wet process, which involves grinding raw materials into a slurry and then feeding them into a rotary kiln for drying and calcination. Total Time: 3 minutes.
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).
Burning: In this operation, the slurry is directly fed into a long inclined steel cylinder called a Rotary kiln. In this kiln there are 3 different zones shown in fig. below Cement Manufacturing Process Flow Chart (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process.

Once the clinkers are cooled, they are ground to a powdered form in tube mills. At this stage, a minuscule quantity (2-3%) of gypsum is added to the mix to coat the cement particles and retard the setting of cement. The desired cement powder is ready and is finally packed and transported. Fig.: Rotary kiln.
