Active Lime Kiln Usage:
Lime can be divided into ordinary lime and active lime according to the nature. The degree of activity is generally less than 200ml, which is mainly used for building and repairing roads. Active lime has a high degree with the value of 300-420ml as well as with advantage of high porosity, high reaction, and low consumption in process, controllable process, widely applied to the steel smelting, calcium carbide, chemical industry, desulfurization and etc.
Active Lime Kiln Main Technical:
The successful industry application of environment-friendly, energy-saving active lime stone with vertical preheated and vertical cooler breaks traditional pattern of lime production. Due to reduction of fuel consumption significantly and reducing exhaust emissions, coupled with the adoption of pulse-packs dust-catcher purify exhaust, not only makes production cost and the energy consumption greatly reduced, but also the calcinations process of emission slandered, environmental condition is kept substantially.
Active Lime Kiln Main Advantage:
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 perheated kiln 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.
8. Environmental protection, the adoption of pulse bag filter dust collecting dust, discharge concentration less than 50mg Nm³/ and below national emission standard (less than 100mg/Nm³)
9. High automation level, the adjustment of production system operation, control and alarm adopts PLC to control in the control centre room, reducing artificial and improving efficiency.
