Jul 31, 2016· PROCESS OF MANUFACTURING OF CEMENT • The process of manufacturing of cement consists of grinding the raw materials, mixing them intimately in certain propor tions depending upon their purity and composition and burning them in a kiln at a temperature of about 1300 to 1500 C, at which temperature clinkers are formed and they are made into ...
These have been used for many years for the less exacting rawmilling process, but recently roller mills, in combination with highefficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient.
The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
