11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
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.
Burning : In this operation, the slurry is directly fed into a long inclined steel cylinder called Rotary kiln.Inthis kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart (i) Drying Zones : In the wet process, the drying zone is comparatively larger than dry process.

The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 - Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately.
Cement Manufacturing Process. for better building CEMENT MANUFACTURING PROCESS All operations of feeding of raw meal, coal, burning, temperature control and cooling are automatic through fuzzy logic / computer control. These operations are controlled from Central Control Room (CCR) which is the nerve center for any cement plant.
kilns - allowed cement manufacture to become a continuous rather than a batch process • Portland cement today, as in Aspdin's time, is a pre-determined and carefully measured chemical combination of calcium, silica, iron and aluminium, yielded by a complex manufacturing process.
Chapter-3 Cement Manufacturing Process 37 the negative air is vented out to the atmosphere. The collected fine powder is retrieved with the help of rapping mechanism and the same is fed to the process.
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process.
