PowerPoint Presentation: THECEMENT MANUFACTURING PROCESS1. RAW GRINDING : The raw materials are very finely ground in order to produce the raw mix . 1. RAW GRINDING Raw grinding and burning 2. BURNING 2. BURNING : The raw mix is preheated before it goes into the kiln, which is heated by a flame that can be as hot as 2000 °C.

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 ProcessFlow Chart (i) Drying Zones : In the wetprocess, the drying zone is comparatively larger than dryprocess. In is because the raw material in slurry form is directly fed into the kiln which has ...

Thecement manufacturing processstarts from the mining of raw materials that are used incement 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.

Cementis so fine that 1 pound ofcementcontains 150 billion grains. Thecementis now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dryprocessis the most modern and popular way to manufacturecement, some kilns in the United States use a wetprocess.
