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.

In the dry process, the raw materials mixed, fined, and then fed into kiln whereas, in the wet process, the raw materials are crushed separately and then directly mixed in correct proportion in the presence of water to make a fine thin paste known as Slurry Must Read Other Powerful Articles Properties of

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.
Production of cement by the dry and wet processes fol- lows the energy and mass flow diagrams shown in . Fig- ures 1. and . 2. respectively. The electrical, manual and combustion energy consumption together with the mate- rial mass flow are allotted to each unit operations with the dry cement operation having five unit operations . and
Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to dry or semidry processes.

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 %).

The 2500t / d cement clinker production line adopts a new dry process, with an annual output of 775,000 tons of cement clinker and a total cement output of 1.05 million tons / year. A cement production line and auxiliary facilities from limestone crushing to cement packaging are constructed.
Dry process cement production kiln is the typical kiln type during the end of the 18th century and the beginning of the 19th century. It is a big step for haft kiln. Because of its less than 1% water content dust raw materials, it reduces the most needed heat for evaporating water.

Following is the procedure of manufacturing cement by dry process using modern technology: Boulders of limestone upto 1.2m size are transported in huge dumpers upto 300kN capacity and dumped into the hopper of the crusher. The hammer mill crushers of single stage are now used for crushing. The crushed limestone now of 75mm size is moved from

In the cement production process, at least 3 tons of materials (including various raw materials, fuels, clinker, mixture, gypsum) should be ground for every ton of Portland cement produced. According to statistics, the dry cement production line needs to be consumed.
Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

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.
