Lime Stone Rotary Kiln


Product introduction
Lime Stone Rotary Kiln is the key equipment in the limestone production process of the building materials industry. Its main function is to calcine the raw materials with high calcium carbonate content such as limestone, dolomite, chalk and shell to produce lime.

A vertical preheater is installed at the kiln to directly transfer the residual heat of the flue gas to the limestone. The temperature of the flue gas can be reduced to below 280℃, which effectively recovers the heat taken away by the exhaust gas, and also reduces the load for subsequent dust removal.

Low pressure loss vertical preheater can effectively improve the preheating effect, the precalcined limestone into the kiln decomposition rate can reach 20-25%, and can directly use 10-15mm fine-grained limestone. The combined scale seals are used at both ends of the rotary kiln to make the air leakage coefficient less than 10%. Composite refractories are used to reduce radiant heat loss. 


Refractory Bricks
The bricks are determined according to the time-proven performance from every aspect such as temperature distribution in the kiln, wear resistance, and scientific properties of the material. As for the joints, dry joints are used normally, while mortar joints are used as needed.
