Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.

Dry process. These are two different processes of manufacturing cement. wet process minerals are wet ground (by adding water) to form a slurry and then dried, dry process minerals are dry ground to form a powder like substance.Both the processes are in use and have their own advantages and disadvantages.While in wet process grinding is easier,in dry process there is a saving in fuel costs

Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water. As shown in the figure it is the upper portion of the kiln.

Cement manufacturing process in summary. Portland cement is manufactured by heating limestone (calcium carbonate) with other materials (such as clay) to 1,450 °C (2,640 °F) in a kiln, in a process known as calcination that liberates a molecule of carbon dioxide from the calcium carbonate to form calcium oxide, or quicklime.
