Technical features of environmental protection lime rotary kiln:
1. The structure of lime rotary kiln is advanced. The vertical preheater with low pressure loss can effectively improve the preheating effect. After preheating, the decomposition rate of limestone can reach 20-25%, and 10-15mm fine-grained limestone can be directly used;
2. Lime rotary kiln reliable rotary kiln at both ends of the combined scale seal. Composite refractories are used to reduce the radiation heat loss when the air leakage coefficient is less than 10%;
3. The circular or square vertical cooler with filling type and divisional ventilation in lime rotary kiln can make the temperature of lime out of the cooler 800C + ambient temperature, which is convenient for transportation and storage, and can preheat the secondary air into the kiln to more than 7000c, reducing the moving parts and special materials.
