In dry process 100 kg coal is required per ton of cement, while in wet process 350 kg coal is required for the same quantity of cement. In 1998 there were 173 large cement plants in India. Out of 173 plants 49 operated on wet-process, while 115 operated on dry process and 9 on semi dry process.
Together, they account for more than 92 of the total cement production. Portland cement, contrary to popular belief, is not a brand of cement, but the most common type which is used as an ingredient in concrete and mortar all around the world. There are a number of uses for cement, and since each use is unique, it needs a different type of cement.
manufacturing process, subject to rigorous control and involving a wide range of operations. Most recently the cement industry has focused a good deal of attention on reducing the environmental impact of cement production particularly carbon-dioxide production 6.2 Portland cement production
Jul 31, 2016nbsp018332Manufacturing of portland cement 1. Manufacturing of portland cement 2. CEMENT- A powdery substance made by calcining lime and clay, mixed with water to form mortar or mixed with sand, gravel, and water to make concrete.
Modern day cement is an unusual industrial product produced in huge quantities in special plants that can produce nothing else. It is produced by a combination of unusual unit operations involving mining, very fine scale blending of raw materials, very high temperature clinkering reactions, controlled cooling, grinding, blending, and finally shipping under controlled conditions.
