The Advanced Interior Structure of Lime Kiln:
Lime kiln has advanced structure. The vertical preheat with low-pressure loss can effectively improve the preheating effect, and the in-kiln decomposition rate of the preheated limestone can reach 20-25% and the 10-15 mm fine particle limestone materials can be directly used.
Processing limestone to lime by lime kilns
The Advantages of Lime Kiln on Technology:
This active lime kiln adopts combined type scale sealing so that the air leakage factor is smaller than 10%. Compound type refractory matter is adopted to reduce radiant heat loss.

The Main Functions and Usage of Lime Kiln:
The infilling type circular or square vertical cooler that can be divisionally ventilated can cool the temperature of the lime to 80℃+ of the environment temperature for the convenience of transportation and storage, and it can also pre-heat the air to over 700℃ to make full use of the waste heat and save energy.
