Contemporary methods of manufacturing cement can be divided into two ways: dry-process cement production and wet-process cement production. The latter measure has been widely utilized in the cement industry; it is a common manufacturing method in which fuel and power consumption have been reduced to a larger extent.

Wet Process. 1. This method is adopted when the raw materials are soft. 2. The quality of cement prepared by this method is superior. 3. Wet process is the fasted method. 4. Raw materials are fed into the rotary kiln in the form of fine powder. 5. This method is widely used. Read Also: Types of Cement Test. Types of Cement. Bogue's Compounds

The materials reach temperatures of 2500°F to well above 3000°F in the kiln. Rotary kilns are divided into two groups, dry-process and wet-process, depending on how the raw materials are prepared. In wet-process kilns, raw materials are fed into the kiln as a slurry with a moisture content of 30 to 40 percent.

Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of …

76 4 Cement Manufacturing—Technology, Practice, and Development Fig. 4.2 Modern dry process cement production process 4.2.4 Manufacturing of Cement Clinker The prepared raw material is called the "kiln feed" and is fed to the kiln. In the kiln, this kiln feed is subjected to a thermal treatment process which consists of

The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.
