ISO9001/ISO14000 International General Active Lime Production Line
The successful industry application of environment-friendly, energy-saving active limestone 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.
Main advantage of lime plant/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 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.

Active lime production line is A line of active lime production.The rotary kiln is the widely-used equipment in calcining active lime. The amount of active lime calcined by rotary kiln accounted for more than 1/3.
Active lime rotary kiln production line is mainly composed of five system: sintering system, materials screen and feeding system, finished product conveying, storage and transportation system, waste gas treatment system, pulverized coal process system. The sintering system is composed of three main equipment: vertical preheater, rotary kiln, vertical cooler.
Limestone is heated by high temperature kiln flue gas in preheater, then it is pushed into the rotary kiln by the hydraulic push rod. The limestone is calcined in rotary kiln under high temperature, then the finished active limestone enter into the vertical cooler. After cooling the active lime will be transmitted into the finished product storage and transportation system. The waste gas will be discharged after processed by waste gas treatment system.
Main products
Vertical preheater
Preheater is polygonal vertical structure, and composed of the top bin, feeding tube, heater body, hydraulic pushing device, transfer chute, etc. The top material bin is equipped with a material level controller to control the material layer height; limestone move into the preheater through sliding tube between top bin and preheater body and have the effect of sealing to prevent the cold air into the preheater.
Rotary kiln
The rotary kiln is the key equipment of the active limestone production line, which is composed of cylinder body, driving device, a supporting device, supporting device of the gear wheel, the seal of kiln head and kiln tail, kiln head cover and combustion device
Vertical cooler
The high temperature materials calcined by rotary kiln is transmitted into the vertical cooler which is made of fire proofing materials. The cooler consists of four cooling discharge area, discharge speed can be controlled separately according to the material temperature. The center air hood and the chamber cooling hood are evenly distributed in cooler, the hoods are connected with fan by pipes. Material layer on the hoods fall down along the generatrix, and contact with cold air which blow up, thus to complete the heat exchange process.
