The use of lime is very wide, common in the field of building, chemical industry, metallurgy, light industry, environmental protection, agriculture, medicament, especially in the industries of steel making, iron making, sintering, copper and aluminum smelting, taking lime as slagging constituent, fibrinolytic agent or sintered material, which play an important role.
Active lime production line developed and designed by our company adopts “Preheater- kiln-cooler Process”, it has better flexibility of raw materials and fuel, with high activity of produced reactive lime, provided excellent raw materials for steel and alumina industry.
Features of chaeng complete system of active lime rotary kiln calcining System:
1. Advanced structure, low pressure drop vertical preheater can effectively improve the preheating effect, limestone after preheated, the decomposition rate is of 20 to 25%, and can take advantage of 10 ~ 50mm of fine grade limestone;
2. reliable modular scales seal of kiln ends, so that air leakage coefficient is less than 10%, the use of composite refractory lining to reduce radiative heat loss;
3. filling-type, round or square vertical cooler can be partition ventilation, make the limestone temperature discharged from the cooler: 80 ℃ + ambient temperature, easy to transport, store, and can make the secondary air into the rotary kiln is preheated to above 700 ℃, reduce moving parts and special materials.
