An interesting case is the Saxon and Norman plants: the 1901 Saxon plant was installed with Schneider Kilns and ballandtube mills, while the "more modern" Norman (1904) had rotary kilns and Griffin mills. However, the Griffin mills were abandoned from 1912 and …
Typical plant costs range upwards of Rs. 1500 crores (USD 250 Million) a fairly substantial fixed investment. In order to pay off this huge capital cost as well as to maintain kiln integrity, the cement plant must produce continuously 3 shifts per day! In addition, the plant must comply with severe environmental constraints.

Aug 09, 2008· Re: Kiln Zone ! The burning zone of a cement kiln is the hottest part of the kiln, under the flame where the final combination into the clinker minerals takes place. Behind that burning zone is the upper transition zone where the temperatures is rising to that in the burning zone.
Jun 20, 2015· This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C. In its simplest form, the rotary kiln is a tube up to 200 meters long and perhaps 6 meters in diameter, with a long flame at one end.
Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.

The Application of Sponge Iron Rotary Kiln: Rotary kiln Sponge Iron belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement.
The fused product is known as the clinkers or raw cement. The size of clinkers varies from 3 mm to 20 mm and they are very hot when they come out of burning zone of kiln. The clinker temperature at the outlet of kiln is nearly 1000°C. A rotary kiln of small size is provided to cool down the hot clinkers.
