What Are the Differences Between the Wet and Dry Processes of a Cement Manufacturer? The wet process of cement manufacturing involves adding water to finely crushed raw material, such as limestone, clay or iron ore, in a proportion of 35 to 50 percent water to 50 to 65 percent raw material to make a slurry that is fed into a cement kiln .
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
Aug 30, 2012· Cement Manufacturing Process Phase II: Proportioning, Blending & Grinding The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding Generally, limestone is 80% and remaining 20% is the clay
AVAILABLE AND EMERGING TECHNOLOGIES FOR REDUCING GREENHOUSE GAS EMISSIONS FROM THE PORTLAND CEMENT INDUSTRY , Rotary kilns are divided into two groups, dry-process and wet-process, depending on how the raw materials are prepared In wet-process kilns, raw materials are fed into the kiln as a slurry with a moisture .
There are two general processes for producing clinker and cement in India : a dry process and a wet process The basic differences between these processes are the form in which the raw meal is fed into the kiln, and the amount of energy consumed in each of the process , Block diagram of cement manufacturing process: 1

Stage of Cement Manufacture There are six main stages of cement manufacturing process Stage 1 Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite The ore rocks are quarried and crushed to smaller pieces of about 6 inch
Cement is so fine that 1 pound of cement contains 150 billion grains The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process
In the case of dry cement production, the raw materials are mixed without water and therefore the evaporation process can be omitted The latter technology could reduction the energy consumption from the ‘wet’ to the ‘dry’ process by over 50% Existing technology in the cement industry ,
