Rotary kiln cement clinker heat mainly by coal combustion, thus adding a direct impact on the amount of coal calcination temperature, as described above, the desired temperature calcining cement clinker is certain, and that certain ingredients of the raw material, calcined maturity material, its theoretical heat consumption is little change. When the device production methods and methods of operation selected, the actual heat consumption should also be small fluctuations, thus requiring appropriate amount of blending, blending amount if less, the calcination temperature drops, will produce a large yellow ball, Rhubarb, raw burn, due to severe burning, reduce the clinker quality, because the kiln temperature decreases, it will result in the kiln edge collapse or collapse kilns and other major incidents. If blending excessive, the situation is more complicated when air supply is sufficient, so that the kiln temperature is too high, the material liquid increases, easy to knot chunks, refining side even knot pillar of fire, seriously affecting refining furnace kiln ventilation affect the yield and quality, and difficult to operate, when the stoker kiln excessive air supply is insufficient, so that oxygen reduction kiln serious reduction is easily formed large, affecting the kiln ventilation, reduce yields and increase the heat consumption, so that the composition of the material into the kiln directly affect the quality of the clinker, but also affect the clinker burning easily through detailed analysis blending accuracy and stability is very important, affecting the quality of clinker and the heat consumption of one of the keys .
