1 Manufacturing Process of Cement
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.

The Cement Manufacturing Process
Wet-process kilns tend to be older operations as compared to dry-processes where raw materials are fed into the process as a dry powder. There are three major variations of dry- process kilns in operation in the U.S.: long dry (LD) kilns, preheater (PH) kilns, and preheater/precalciner (PH/PC) kilns.
