Production Process introduction
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 degrees Celsius, 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.

The process advantage
The calcination process adopts pre-heater+ rotary kiln+ vertical cooler system, , it can reduce the fuel consumption 40%, increase output capacity 30% due to reuse the waste gas in the system. The other advantages are in the following.
1. The lime quality is very good and high activity.
2. It is especially suitable for large-scale lime production.
3. The production running is stable, the whole process using negative pressure, air flow freely and high production safety
4. Using the bag filter system, it can reduce the exhaust gas less than 50mg/Nm3
5. It shorten kiln length, reduce heat loss and area.
6. Cooler and kiln hood cover designed together, good seal, saving area.
