Active Lime Rotary Kiln Production Line, Limestone Production Plant, Mini High Temperature Horizontal Indirect Active Lime Rotary Kiln Price
1. Introduction of High Efficiency Rotary Kiln Active Lime Production Line
Active lime kiln is a type of rotary kiln and it is the main equipment used for calcining active lime. This equipment is mainly composed of the cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln. Active lime kiln has the advantages of simple structure, reliable operation and easy control of the production process.
2. Advantages of High Efficiency Rotary Kiln Active Lime Production Line
1. Good quality and high output, suitable for large-scale activity of lime production line and large-scale production.
2. Stable production, all the production with the negative pressure, air flow and higher security.
3. Simple structure, easy control and beneficial operation and maintenance.
4. Fine grade limestone can be calcined, full use of mine resources.
5. Low heat consumption per unit of product, installation in vertical kiln perheater which can take advantage of exhaust warm limestone, greatly reducing the fuel consumption.
6. Making full use of industrial waste gas as a fuel for lime burning (such as blast furnace exhaust gas, acetylene tail gas, charcoal blue exhaust, etc)
7. Kiln head adopts the design of vertical cooler integrating kiln head cover. The construction area is small, good sealing, effectively avoiding hot waste gas emissions unsystematically.
3. Performance of High Efficiency Rotary Kiln Active Lime Production Line
Active lime kiln has advanced structure. The vertical pre-heat with low-pressure loss can effectively improve the pre-heating effect, and the in-kiln decomposition rate of the pre-heated limestone can reach 20-25% and the 10-15mm fine particle limestone materials can be directly used.
4. Feature of High Efficiency Rotary Kiln Active Lime Production Line
Active lime kiln has advanced structure. The vertical pre-heat with low-pressure loss can effectively improve the pre-heating effect, and the in-kiln decomposition rate of the pre-heated limestone can reach 20-25% and the 10-15mm fine particle limestone materials can be directly used.
5. Principle of High Efficiency Rotary Kiln Active Lime Production Line
This active lime kiln adopts combined type scale sealing, so that the air leakage factor is smaller than 10%. Compound type refractory matter is adopted to reduce the radiant heat loss. The infilling type circular or square vertical cooler that can be divisionally ventilated can cool the temperature of the lime that is discharged from the cooler to 80ºC+ of the environment temperature for the convenience of transportation and storage, and it can also pre-heat the in-kiln secondary air to over 700ºC to make full use of the waste heat and save energy.
