The dry process for the manufacture of cement is preferred only in places where hard crystalline limestone and shales are available. The only advantage of this process is that the fuel consumption is low. The raw materials are first crushed together in the dry state in a multi-chamber tube mil of a fairly large diameter. The drying unit consists of a grade firing with an induced draught fan

In dry and semi-dry processes for the manufacture of cement, raw materials are crushed and fed into the grinder in the correct proportions. The raw material is dried and reduced in size to a fine powder in a grinder. Dry powder is called a raw meal. Raw meals are pumped into mixing silos. Adjustment of the proportions of materials required for cement manufacturing is made in silos.
The flow diagram of cement manufacture is given below: Coal Requirement: 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
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.
The new dry-process cement production line technology was developed in the 1950s, so far, the new dry process cement equipment rate of Japan, Germany, and other developed countries have accounted for 95%. This cement production process regards the suspension preheating and pre decomposition as the core, and has the advantages of small pollution and a high degree of automation. At present, its

In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo. Adjustment in the proportion of the materials required for the manufacture of
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.

The dry process of cement manufacturing means that after raw materials with different particle sizes are dried, broken and ground into powders of certain fineness, they will be sent into the dry process kiln for calcining, finally forming clinker. Besides, the raw material powder can also be made into raw material balls by adding a proper amount of water and then be directly sent to the Lepol
Note. To produce one tone of cement, 100 kg coal is used. All cement plants after 1980’s use the dry process for manufacture of cement. In wet process to make one tone of cement, 350 kg of coal is used. Burning & grinding process remains same for both dry & wet process.

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 easier,in dry process there is a saving in fuel costs
Dry Process. 1. This method is adopted when the raw materials are hard. 2. The quality of cement prepared by this method is inferior.. 3. The dry process is slow, difficult and costly.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix 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. The two processes are

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.
