Introduction of Active lime rotary kiln
●The active lime rotary kiln has an advanced structure. The vertical preheater with low pressure loss can effectively improve the preheating effect. The decomposition rate of the preheated limestone into the kiln can reach 20-25%, and 10-15mm fine-grained limestone can be directly used ；
●Reliable active lime rotary kiln with combined scale seal at both ends of the rotary kiln. Use composite refractory materials to make the air leakage coefficient less than 10% to reduce radiant heat loss;
●Active lime rotary kiln filled, circular or square vertical cooler with partition ventilation, the lime temperature out of the cooler is 800C + ambient temperature, which is convenient for transportation and storage, and can preheat the secondary air entering the kiln to 700°C Above, moving parts and special materials are reduced.
