Application and Benefits of Limestone Rotary Kiln

Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory. This limestone rotary kiln can produce lime with advantages of strong ability to react chemically, low volume density and large specific surface. 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 rotary kiln 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.

The lime quality of horizontal lime kiln production first is dependent on the amount of calcium oxide and magnesium oxide, the second is to look at birth burnt lime burning rate, and burning of birth is part of the incomplete decomposition of limestone, whereas more than burned calcined limestone. This lime activity of the part is low, it is difficult to distinguish between ordinary limestone behind production, and normal combustion temperature is 1000 ℃ 1200 ℃. Burnt-out ash is usually high combustion temperature, and time is long, the surface crack or glass shell, volume shrinkage, the color of the blackened, increase the capacity. The processing of burnt, of course, first consider the air-fuel ratio is too big or not, should be adjusted to a reasonable composition with quantity. Of course, we also must fully consider the coal quality. Also should adjust the wind to adapt it.

The features and benefits of the limestone rotary kiln areas follows:

1. Energy conservation, waste gas as the second useful source, recycling economy;

2. PLC...
