Rotary kiln is the main equipment of active production line. The calcined limestone quality of rotary kiln has a larger impact on the production quality of the whole production line. Good limestone production line, to a large extent, determines the enterprise product quality, yield and cost.

The lime quality of rotary 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.
