Lime Rotary Kiln Equipment Environmental Protection And Durable

Introduction of lime production line:
Lime production line refers to the whole process equipment line of 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: Raw material preparation
1. Limestone: The particle size of limestone should be between 10 and 40mm. The proportion of limestone above 40mm or below 10mm should not exceed 5%. The maximum dimension should be less than 40mm.
2. Fuel: Furnace gas, coal gas, coal bed methane and pulverized coal can be used as fuel.


The second step: raw material feeding
The limestone in the factory area is shoveled to the hopper by the tractor, unloaded from the hopper to the vibrating feeder, and sent to the vibrating screen by the belt conveyor for screening. The size of ≥20mm is sent to the preheater by the conveyor. Dimensions smaller than <20mm will be taken away.


Step 3: Limestone calcination
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, it is calcined at a temperature of about 1300 °C , the decomposition of limestone 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
There are two kinds of dust filtration systems. One is at the kiln mouth. 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, and the dust is discharged into the air after being filtered by the cloth bag.
