How Cement is Made
There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches.

cement
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).

In the case of dry cement production, the raw materials are mixed without water and therefore the evaporation process can be omitted. The latter technology could reduction the energy consumption from the 'wet' to the 'dry' process by over 50%. Existing technology in the cement industry can be upgraded in several ways.

Good Practice in Cement Production: Dry Process Kilns
There are two basic types of cement production processes and a number of different kiln types. Cement production is either "wet" or "dry", depending on the water content of the material feedstock. A good practice in the cement industry is to utilize dry kiln processes whenever possible. Endorse Newsletter Get toolbox updates by e-mail

Cement – Analysis
Globally, the thermal energy and electricity intensities of cement production have gradually declined over the past decades as dry-process kilns – including staged preheaters and precalciners (considered state-of-the-art technology) – replace wet-process kilns, and as more efficient grinding equipment is deployed.

Dry Process
The dry process was developed in the late 1960s and is widely used today. UF6 is vaporized from steam or hot-water-heated vaporizing baths, and vaporized UF 6 is introduced into the feed end of a rotating kiln. Here, it meets and reacts with superheated steam to give a plume of uranyl fluoride (UO 2 F 2 ).

Wet Process of Cement Manufacturing
This method is called a semi-dry process, which belongs to the cement dry process production. Advantages: as the dry process is to directly feed raw material powder into the rotary kiln for calcination, and the moisture content of raw materials is about 1% – 2%, it saves the heat consumption needed for the moisture evaporation.

Cement Manufacturing Process: How the Cement is Made?
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.
