The Cement Plant Operations Handbook. The Cement Plant Operations Handbook for dry process plant by Philip A Alsop, PhD. Covering some 232 pages, the cement industry''s favorite technical reference book provides indepth information of the various aspects of cement production plant from raw material extraction to the finished product.
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.
