Rotary Kiln Cement plant - Manufacturing Process

	Crushing & Proportioning : - In cement manufacturing process the main raw material is limestone, which is crushed and transported to the pre-blending stockpile by means of a belt conveyor. After reclaiming it is stored into the respective hoppers along with other Raw materials. These raw materials then extracted in desired proportion with the help of electronic weigh feeder & transported to the raw mill for fine grinding.
	Raw milling & Blending : - The raw mill is a closed circuit ball mill equipped with high efficiency separator. After grinding to 90 microns size the raw meal is send to the continuous blending silos (CFC) for homogenization & extracted by means of load cell hopper for feeding to the kiln pre heaters.
	Pyro processing : - It consists of series of low-pressure drop, pre heater cyclones generally with fluidized bed calciner, where the calcinations begin and material goes into the Rotary Kiln and after clinkerization the hot material is sent to the cooler for its cooling. The cooler is efficiently designed to recover maximize heat while cooling the hot clinker which is then crushed & sent to the stock pile for intermediate storage.
	Burning :- The required temperature for the clinkerisation is about 1500oC, which can be attained either by Coal, Gas or Oil. The burner is fuel-efficient specially designed Multi channel type for uniform burning.
	Cement milling, Storage & Packing:- The clinker mixed with app. 5% of gypsum is sent to the cement mill (Ball Mill) for fine grinding to produce cement. It is then transported to CFC silo for blending & storage and is packed in the bags with helps of auto packers & transported to the market for sale
