White Cement Manufacturing
White Cement Plant. The production process of white Portland cement is quite different from ordinary Portland cement. It is unique in both process flow and cement equipment selection. In white cement plants, the main manufacturing process includes six steps: raw material crushing, raw material grinding, clinker calcination, clinker cooling, cement grinding, and cement packing.

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.

Manufacturing of Portland Cement – Process and Materials
The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker …
