Introduction of lime production line:
Lime production line refers to the whole process equipment line for active lime production. Among all active lime production processes, the rotary kiln production process is the most advanced one. Our production process uses a rotary kiln with a vertical preheater and a vertical cooler to calcine limestone to meet the production requirements of high efficiency, energy saving, environmental protection and high activity.
Process flow of lime production line:
Step 1: prepare raw materials with a particle size between 10-40mm
<Available fuel: Furnace gas, coal gas, coal bed methane and pulverized coal can be used as fuel. >
Step 2: the raw materials are unloaded from the hopper to the vibrating feeder, and the raw materials <20mm are screened out by the vibrating screen and sent to the preheater.
Step 3: Calcining the 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 a temperature of about 1300°C, the limestone decomposes and releases CO2 to complete the formation of quicklime.
Step 4: Finished Product Delivery
The lime is discharged from the vibrating feeder at the bottom of the vertical cooler to the chain conveyor, and is lifted into lime in the storage hopper, which can be used for dispatching or transported to the hydration workshop.
Step 5: Dust Filtration System.here are two types of dust filtration 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 from the lime storage hopper and the feeding part of the bucket elevator. The dust is filtered by the cloth bag and then discharged into the air.
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, all production adopts negative pressure and airflow, which is more safe.
3. Simple structure, convenient control, convenient operation and maintenance.
4. Fine-grade limestone can be calcined, making full use of mine resources.
5. The heat consumption per unit product is low. It is installed in the superheater of the shaft kiln, and the exhaust gas temperature limestone is used to greatly reduce the fuel consumption.
6. Make full use of industrial waste gas as fuel for burning lime (such as blast furnace tail gas, acetylene tail gas, carbon blue tail gas, etc.)
7. The kiln head adopts a vertical cooler integrated kiln head cover design. Small construction area, good sealing, effectively avoid unsystematic discharge of hot exhaust gas
