The advantages of rotary kilns for lime calcination
Rotary kilns make it possible to obtain high-quality soft-burned lime from small-sized limestone and from soft carbonate rocks (chalk, tuff, shell limestone).
The advantages of rotary kilns for lime calcination are as follows: The second most important technological advantage of lime calcination in rotary devices is the short time it takes for the material to pass from the place of loading to the exit from the kiln, which ensures efficient process control. In addition, rotating units provide a compact technological scheme, allow you to automate the process of burning limestone and reduce capital costs for the construction of workshops. In limestone rotary kilns, high quality lime can be obtained by firing at medium and fairly high temperatures. Due to the short residence time of the material in the drum, the risk of overburning in them is minimal. At the same time, lime is much more homogeneous in composition and contains fewer impurities.
Advantages of rotary kilns:
1) high quality lime;
2) use of any raw materials;
3) the use of any type of fuel;
4) obtaining any kind of lime (construction, metallurgical)
