High Activity Energy Saving Lime Rotary Kiln Environmental Protection

Introduction of active lime rotary kiln production line:
Active lime production equipment----Lime production line is a complete set of lime production equipment from feeding equipment, screening equipment, conveying equipment, calcining equipment, dust removal and unloading equipment. Rotary kiln calcined limestone with preheater and vertical cooler meets the production requirements of high efficiency, energy saving, environmental protection and high activity. Successful industrial application of vertical preheating of environmentally friendly and energy-saving activated limestone. Due to the significant reduction in fuel consumption and tail gas emissions, coupled with the use of pulse bag dust collectors to purify tail gas, not only the production cost and energy consumption are greatly reduced, but also the emissions during the calcination process are up to standard, and the environmental conditions are basically maintained.


Process flow of lime production line:

Step 1: The raw materials are crushed to a particle size between 10-40mm. The raw materials are discharged from the hopper to the vibrating feeder, and the raw materials <20mm are screened by the vibrating screen and then sent to the preheater.

 

Step 2: Rotary kiln calcining lime. The limestone in the preheater is preheated by hot air, and then discharged into the rotary kiln through the chute connecting the preheater and the kiln, and stays in the kiln for 1.5-2 hours for calcination. During this process, calcined at temperatures around 1300°C, the limestone decomposes and releases CO2 to complete the formation of quicklime.


Step 3: After the lime is cooled by the cooling equipment, it is discharged from the vibrating feeder at the bottom to the chain conveyor, and is lifted into lime in the storage hopper, which can be used for scheduling or transported to the hydration workshop.

 

Step 4: Use two dust filter systems. One is at the mouth of the kiln. After the dust is filtered by the bag filter, the clean gas is discharged into the air. The other is the dust in the lime storage hopper and the feeding part of the bucket elevator. The dust is discharged into the air after being filtered by a cloth bag.

Main advantages of quicklime plant/lime production line
1. With good quality and high output, it is suitable for large-scale activities and large-scale production of lime production lines.
2. The production is stable, and all production adopts negative pressure airflow, which is safer.
3. Simple structure, convenient control, convenient operation and maintenance.
4. Fine-grade limestone can be calcined, making full use of mine resources and reducing the loss of raw materials.
5. Low heat consumption per unit product. It is installed in the superheater of the shaft kiln and adopts limestone with exhaust gas temperature, which greatly reduces the fuel consumption.
6. It can make full use of industrial waste gas as the fuel for burning lime to reduce costs.
7. The kiln head adopts a vertical cooler integrated kiln head cover design. The construction area is small, the sealing performance is good, and the unsystematic discharge of hot exhaust gas is effectively avoided.
