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.

5 CEMENT –HISTORY In India, Portland cement was first manufactured in 1904 near Madras, by the South India Industrial Ltd.But this venture failed. Between 1912 and 1913, the Indian Cement Co. Ltd., was established at Porbander (Gujarat) and by 1914 this Company was able to deliver about1000 tons of Portland cement. By 1918 three factories were established.

process requires a high amount of energy, mainly to evaporate the water in the slurry and become uneconomic and largely abandoned. The energy requirement to pro-duce cement in dry route is approximately half of the energy required to produce it through the wet process. The most common way to manufacture Portland cement is through a dry process.
