(II) Wet Process (Old Technology): In the earlier part of the century i.e., from 1913 to 1960, the wet process was used for the manufacture of cement. From 1913 onwards, the cement industry underwent a number of changes mainly to suit the requirements of the manufacturers and the govt. policies till early 1982.

 · Five different processes are used in the portland cement industry to accomplish the pyroprocessing step: the wet process, the dry process (long dry process), the semidry process, the dry process with a preheater, and the dry process with a preheater/precalciner. Each of these processes accomplishes the physical/chemical steps defined above.

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.

Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form …

dry process cement plant and a mathematical programming model capable of suggesting the best cost effective strategy was outlined. Control costs consisting of operating and investment costs along with the efficiency of control options were taken into account in the model. A representative case study from the cement industry was considered in

 · future, the wet process will not necessarily be required. Cur-rently, all cement plants in Tanzania use the technology based on the dry process. In the final stage of production, Portland cement is pro-duced by intergrinding cement clinker with sulphates such as gypsum and anhydrite in order to obtain a fine homoge-neous powder.

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 cement industry recognizes its responsibility to manage the environmental impact, associated with the manufacturing of its product. Mainly, there are two types of cement production process; such as wet process and dry process. The preparation of cement includes mining, crushing, and grinding of raw materials, calcining the materials in 1408

 · Cement production processes are generally distinguished into wet process, semi-wet process, semi-dry and Lepol process, and dry process. For the production of clinker, the two types of kilns used are rotary kilns and shaft kilns (Hendriks et al., 2004). The world average p's rimary energy intensity is approximately 4.8 MJ/kg cement, with the ...

 · Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions that occur independently of the mixture's water content; they can harden even underwater or when constantly exposed to wet weather.
