Active lime kiln is a type of rotary kiln and it is the main equipment used for calcining active lime. This equipment is mainly composed of the cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln. Active lime kiln has the advantages of simple structure, reliable operation and easy control of the production process.
Active lime kiln has advanced structure. The vertical pre-heat with low-pressure loss can effectively improve the pre-heating effect, and the in-kiln decomposition rate of the pre-heated limestone can reach 20-25% and the 10-15mm fine particle limestone materials can be directly used.
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 the radiant heat loss. The infilling type circular or square vertical cooler that can be divisionally ventilated can cool the temperature of the lime that is discharged from the cooler to 80℃+ of the environment temperature for the convenience of transportation and storage, and it can also pre-heat the in-kiln secondary air to over 700℃ to make full use of the waste heat and save energy.
