High Efficiency Quick Lime Plant
Product Description
Working principle of high efficiency quick lime plant:
1.Raw material feeding
The limestone in the plant yard will be carried by tractor shovel and feed to hopper, it will be discharged from hopper to vibrating feeder and sent to vibrating screen for screening through belt conveyor. The size ≥20mm will be sent to pre-heater by conveyor. And size less < 20mm will be carried away.
2.Calcination
The limestone in the pre-heater will be preheated by the hot air, then it will be discharged to rotary kiln though chute that connecting pre-heater and kiln, it will stay in the kiln for 1.5-2 hours for calcination, during the process, it will be calcinated with a temperature around 1300 ℃, limestone decomposition, release of CO2, become quicklime. Then the lime moves to vertical cooler for cooling.
3.Lime conveying
Lime will be discharged to a chain conveyor by vibrating feeders in the bottom of vertical cooler, it will be lifted to storage hopper by bucket elevator. So the lime in the storage hopper for dispatch or hydration workshop.
4.Dust filtering .
There are two dust filtering systems, one is in the kiln inlet, dust will be filtered by bag filter then the clean gas will release to air. The other is dust from lime storage hopper and feeding of bucket elevator will be filtered by bag filter then release to air.
Lime Rotary kiln Advantages:
1.Simple structure of kiln process, easy operation and great output, extraordinarily suitable for large-medium lime production line.
2.High activity degree of lime produced in the process of rotary kiln, namely, 340~380ml in common, even up to 400ml.
3.Low rate of the less burned and the over burned in the process of rotary kiln, equal and stable quality of products.
4.Rotary kiln process can straightly calcine 10~50mm fine-sized limestone.
5.Kiln process has low integrated power consumption and can apply coal powder as fuel.
6.Both of gas fuel and solid fuel can be used for preheater – rotary kiln – cooler process, d
epending on conditions of local resources. Coal powder, BF gas, natural gas, or heavy oil can be used as roasting fuel.
