The rotary kiln, also called the kiln dryer, cement rotary kiln and lime rotary kiln, is a type of rotating calcining kiln used in the industries of construction materials, metallurgy, chemical engineering and environmental protection.
Rotary lime kiln is also called lime rotary kiln or limestone rotary kiln. It is used for the calcination of limestone to make quicklime. And specifically speaking, it is a slightly horizontal device that can rotate continuously to burn down the limestone thoroughly to make quicklime.
The rotary lime kiln is slightly inclined to horizontal and rotates on a set of riding rings. Traditionally, in order to burn down the limestone thoroughly, rotary lime kiln is often very long. However, modern rotary lime kiln tends to be shorter and is equipped with pre-heater and cooler to save energy as well enhance quicklime plant efficiency.
Lime rotary kiln is also called roller rotary kiln. To make sure its air leakage coefficient is less than 10 percent, lime rotary kiln adopts advanced structure and reliable combined scale-like seal in both ends. It also uses composite refractory to reduce the loss of heat radiation.
Rotary kiln has a high output and is very suitable for large-scale active lime production line. Now there are 2200 tons of lime rotary kiln in the world, and many 150-300 tons of lime rotary kilns have been built at home and abroad, which run well and are also suitable for the application of small and medium-sized lime enterprises.
Lime rotary kiln structure is advanced and simple. The vertical preheater can effectively improve the preheating effect, the preheated limestone enters into the rotary kiln and is calcined at the best calcination temperature of 900 1100 , the decomposition rate is up to 20 - 25, more efficiently the sealing system at both ends of the ...

Rotary lime kilns typically have four refractory zones with varying types of refractory. Long process kilns require abrasion resistant, high strength alumina brick for the charging zone. The charging zone is where the abrasion of the stone can be particularly severe. Short preheater kilns normally do not have a charging zone that sees high ...
