2020-2-27 Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water. As shown in the figure it is the upper portion of the kiln.

2020-7-9 Based on the technic adopted for mixing raw materials the manufacturing process of cement is divided into wet process and dry process. Wet process is normally used now a days. But dry process is also gaining popularity due to their energy efficiency and when the ingredients are hard. MANUFACTURING PROCESS OF CEMENT-WET PROCESS

2021-6-15 The total consumption 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. 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, and lime, silica and alumina ...

2021-6-17 This process was especially evolved to counter the main drawback of the wet process i.e. high fuel consumption. In this process, the raw materials ground in dry condition are homogenized and then nodulised in a pan noduliser of dish or rotary type by adding controlled quantity of water (10- 12 %).

2021-6-14 All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.

2021-6-14 In dry process 100 kg coal is required per ton of cement, while in wet process 350 kg coal is required for the same quantity of cement. In 1998 there were 173 large cement plants in India. Out of 173 plants 49 operated on wet-process, while 115 operated on dry process and 9 on semi dry process.

Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.

2020-4-9 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.
Read MoreIn a wet process, the material is in the kiln for 2 to 3 hours. This time is reduced to 1 to 2 hours for a dry process. Some new heat exchanges only require 20 minutes. Thus the dry process requires significantly lesser fuel compared to the wet process. Quantity of coal required to produce 1 Ton of cement is only about 100 kg in case of dry ...

Portland cement is used around the world and used as a simple component of concrete, mortar, plaster etc. the dry process is used when raw material are relatively hard. This process is slow and its creation is expensive. The wet process consist many operation like mixing, burning and grinding to manufacture the cement.
