At present, it has been one of the most preferred auxiliary equipment for steel-making, coking and calcium carbide industries. Moreover, it is also the best kiln type in limestone industries for its strong adaptability to raw and fuel materials, convenient maintenance and low consumption benefits.As the lime pit adopts new modern technology of burner, it can make full use of cheap energy; especially utilize the most draining inflammable gas as treasure of part energy, which is harmful to the environment. Thus, it not only protects environment, but also is in line with the public policy documents on response to energy conservation, emission reduction and low carbon. This machine can produce lime with advantages of strong ability to react chemically, low volume density and large specific surface.Its process is that limestone and fuel into the lime lime rotary kiln (if the gas fuel pipe and the burner into) is preheated to 850 ℃ beginning to take off the carbonate decomposition, to 1200 ℃ calcination, then after cooled , and unloaded out of kiln. All its calcination process is equivalent to being in an airtight container. Different calcination rotary kiln types have different preheating, cooling and discharging mode. But there are several process principles alike: calcination temperature is at 850-1200 degree and the preheating temperature is at 100-850 degree. Ash temperature is at 100℃. Raw material is with high quality, lime quality is good; fuel calorific value is high, number of consumption is low; Limestone particle size is proportional to the calcining time. Quick lime activity degree is inversely proportional to calcination time, and calcination temperature. In accordance with different ways of adding grease, select adding grease variety where use the grease. Because the ways to add grease are grease gun or use grease cup to add grease on the bearing; centralized greasing; some closed places permanent use after adding. In the use of grease should be used...
