Lime rotary kiln structure of advanced, low pressure loss of the vertical preheater can effectively improve the preheating effect, the preheated limestone into the kiln decomposition rate of up to20-25%, and the direct use of 10-15mm fine-grade limestone.
Lime Rotary Kiln combined flake seal at both ends. So that the air leakage coefficient is less than 10%. The use of composite refractory to reduce radiant heat loss; lime rotary kiln filled, can be partitioned circular or square vertical cooler, the cooler temperature of the lime is 800℃ + ambient temperature, conveying, storing, and can be preheated into the kiln secondary air above 7000℃, reducing the movement of parts and special materials.
Lime rotary kiln design should meet the following requirements:
1. Lime kiln specifications should be based on the firing system of production requirements, combined with raw materials,fuel conditions and preheater, calciner, cooler configuration and other factors determined.
2. Preheater kiln and precalciner kiln aspect ratio (L / D) should take 11-16.
3. Preheater kiln and precalciner slope should be 3.5% -4%; maximum speed: precalciner should be 3.0-3.5r / min, preheater kiln should be 2.0-2.5r / min; speed range 1:10.
4 Lime rotary kiln firing belt cooling should adopt forced air cooling.
5. Lime kiln burning zone should have the cylinder temperature detection measures.
6. The main motor lime kiln should adopt continuously variable speed motor, and need to set up auxiliary transmission,auxiliary transmission should have standby power.
Lime rotary kiln with larger diameter,shorter kiln length, two-point support of the kiln, both to reduce the kiln body up and down the rate of movement, but also save space; using frequency control motor driven kiln, and with auxiliary motor, stable work, easy toad just; Kiln head and tail without spring leaf seal structure, simple and reliable.Lime rotary kiln structure of advanced, low pressure loss of the vertical preheater can effectively improve the preheating effect, the preheated limestone into the kiln decomposition rate of up to20-25%, and the direct use of 10-15mm fine-grade limestone.
