Active Lime Production Line

Description of Active Lime Production Line

This active lime production line is a complete line that includes vertical preheater, rotary kiln, grate cooler, air treatment system, raw material conveyor system, finished product conveyor system, raw coal grinding system, and so on. central control system is employed to make concentrated operation management.

The processing flow of lime production line

Qualified limestone stores in silos and be shipped through the pre-heater by the elevator into the silos which is on the top of the pre-heater. The pre-heater on the top of silos is consisted of top and bottom level meter controllers which control the feeding capacity.Then through the feed tube the limestone is distributed to the indoor compartment of the pre-heater.

The limestone in the pre-heater is heated to around 900 by the kiln flue gas of 1150 . At this time, about 30% of the limestone has been decomposition. Then the limestone is put into the rotary kiln by the hydraulic stem. In the rotary kiln the limestone sinters and decomposes into CaO and CO2. Then the decomposed limestone goes into the cooler and is cooled to about 100 by the cold air and then is discharged. The 600 hot air after heat exchange goes into the kiln and combusts with gas. The Exhaust gas blended with the cold wind go to the bag filter through the suction fan and then through the exhaust fan into the chimney.

The limestone out of the cooler enters into the lime storehouse through the vibrating feeder, chain bucket conveyor, bucket elevator and belt conveyor. Whether to carry out screening and other procedures depends on customer requirements.

Active Lime Production 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.
