Active Lime Production Line EPC Project

Active Lime Production Line Description:

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.

Active Lime Production Line Process:

1. Raw Material Conveying:

The 20-40mm limestone on the stock ground is sent to storage silo by the belt conveyor with large inclination. In the storage silo, qualified limestone with granularity be sent to the gravel silo, while limestone with particle size less than 10mm will be conveyed to the powder silo.

2. Limestone Calcining:

Preheater is heated by high-temperature gases from rotary kiln to 600-800℃, at which temperature limestone can be partly decomposed. Then the limestone will be sent to the kiln end, where it will undergo high-temperature calcination before sent to the vertical cooler. The processed limestone will be cooled down by cold air to 65℃.

3. Finished Product Conveying:

The final lime will be sent to the storage bin for final products by bucket elevator. After screening, qualified lime whose particle size will be sent to storage for active lime.

4. Waste Gas Treating:

High-temperature gases from rotary kiln will do heat exchange with limestone inside the preheater, and after that, the temperature of these gases will reduce to lower 280℃. Then these gases will be cooled down by multi-tube cooler to 200℃ lower. Finally, they enter into the bag filer before discharged into the atmosphere.
