Quick Lime 50t/D 1200t/D Coal Fired Complete Plant

Medium Scale Coal Fired Complete Plant For Producing Quick Lime

 

 

Prodiction Process
Step One Raw Material Preparation
1. Limestone: The particle size of limestone should be between 10~40mm. The porportion of limestone size above 40mm or below 10mm should not be more than 5%. The maximum size should be less than 40mm.
2. Fuel: Furnace gas, gas, coalbed methane, pulverized coal couldbe used as fuel.

 

Step Two. Raw material feeding
Limestone in the plant yard will be carries by tractor shovel and feed to hooper, it will be discharged from hooper to vibrting feeder and sent to vibrating screen for screening through belt conveyor. The size ≥20mm will be sent to preheater by conveyor. And size less than 20mm will be carried away.

 

Step Three. Limestone Calcination
Limestone in the preheater will be preheated by the hot air, then it will be discharged to rotary kiln through chute that connecting preheater and kiln, it will stay in the kiln for 1.5- 2 hours for calcination. During the process, it will be calcined to 1300 ℃ temperature. After that, it comes limestone decomposition and release of co2, then quick lime production will be completed.

Step Four. Finished Products Conveying
Lime will be discharged to a chain conveyor by vibrating feeders in the bottomof vertical cooler, it will be lifted to lime in the storage hopper can be usedfor dispatch or transported to the hydration workshop.

 

Step Five. Dust Filtering System
There are two dust filtering systems, one is in the kiln inlet, dust will befiltered by bag filter then the clean gas will be released to air. The other isdust from lime storage hopper and the feeding part of bucket elevator, dustwill be filtered by bags and then released to air.
