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.
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.
Manufacture of Portland Cement Cement is made by heating limestone (calcium carbonate) with small quantities of other materials (such as clay) to 1450 °C in a kiln, in a process known as calcination, .

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.
