Installation Site of Environmental Protection Lime Rotary Kiln in Philippines
For more information about the rotary kiln installation site, we can also contact us for more information on site inspection and site inspection!
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. The decomposition rate of limestone after preheating can reach 20-25%, and 10-15mm fine limestone can be used directly;
2. The lime rotary kiln has reliable scale seal at both ends of rotary kiln. Make the air leakage coefficient less than 10%, use composite refractory to reduce radiation heat loss;
3. The circular or square vertical cooler with filling type and divisible ventilation for lime rotary kiln can make the temperature of lime out of cooler be 800C + ambient temperature, which is convenient for transportation and storage, and can preheat the secondary air into kiln to above 7000c, reducing moving parts and special materials.
