The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energyintensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 a decline of 89 percent while the number of dry process kilns has only been reduced from 198 to

The sludge may undergo one or several treatments resulting in a dry solid alternative fuel of a low to medium energy content that can be used in cement industry. The use of sewage sludge as alternative fuel is a common practice in cement plants around the world, Europe in particular. It could be an attractive business proposition for wastewater treatment plant operators and cement industry to

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called

Process water is not required in a dry process cement plant. However if an ESP is used to clean preheater exhaust gases, a cooling tower is necessarily installed to bring down the temperature to about 140 °C. Gases are cooled by spraying water on the gases in the cooling tower. Water evaporates and is consequently lost.

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 essentially alike except in the wet process, the raw materials are ground with water before being fed into the kiln.

Stage of Cement Manufacture. There are six main stages of 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 to smaller pieces of about 6 inches.

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.

· 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 multichamber tube mil of a fairly large diameter.
