Performance characteristics of lime rotary kiln
1.The structure of the lime rotary kiln is simple, the low pressure loss of the vertical preheater can effectively improve the preheating effect, the decomposition rate of preheated limestone into the kiln can reach 20-25%, and can directly use 10-15mm fine-grained limestone;
2.Lime rotary kiln reliable rotary kiln at both ends of the combined scale seal. Make the air leakage coefficient less than 10% use composite refractories to reduce radiant heat loss;
3.The circular or square vertical cooler filled with lime rotary kiln and can be ventilated in zones, the lime temperature of the cooler is 800C+ ambient temperature, which is easy to transport and store, and the secondary air into the kiln can be preheated to more than 7000C, reducing moving parts and special materials.
4.High quality raw materials, good lime quality; High calorific value of fuel and low quantity consumption.
5.Limestone particle size and calcination time is proportional; The activity of lime is inversely proportional to calcination time and calcination temperature.
