1. Introduction of Energy Saving Limestone Calcination Process Production Line
Lime rotary kiln are used for produce active lime and light burned dolomite used in steel roasting plants and ferroalloy Factory.
Lime kiln main subsidiary equipment are feeding mechanism, distributing device, wind supply device, burning device, ash discharging device, etc. Relatively speaking, co-firing lime kiln material distributing is very critical because it feed the fuel and limestones into kiln simultaneously, and must achieve burden are reasonable distribution in the kiln, eliminate the furnace wall effect, balanced resistance in furnace, to achieve whole furnace section of "lit" uniform. Therefore, the form and effect of distributor has a great influence on the productivity of lime kiln.

2. Advantages of Energy Saving Limestone Calcination Process Production Line
1. Advanced structure, low pressure loss of vertical preheater can effectively improve the preheating effect, after preheated limestone enter into kiln, the decomposition rate can achieve up to 20-25%, and can use 10-15mm fine grade limestone directly..
2. Rotary kiln each ends are modular sealing. So that air leakage coefficient less than 10%, using composite refractory to reduce radiant heat loss.
3. Filling, Can partition ventilation round or square upright cooler, make sure the lime outlet from cooler temperature 800C+environment, easy to transport, store, and the secondary air into the furnace preheated to 7000C or more, reducing the moving parts and special materials.

3. Structure of Energy Saving Limestone Calcination Process Production Line
1. Advanced calcination mechanism, energy-saving calcinations method.
The kiln body of rotary kiln uses fully sealed calcining mechanism, which is advanced and scientific. The kiln refractory insulation layer adopts multi-layer refractory with good lightness. Meanwhile, the upper part and lower part of the kiln use heat exchange method, which reduces the heat loss to the maximum limit. High heat efficiency.
2. Higher production efficiency, better finished product quality.
Materials move and roll more smoothly and stably inside the kiln, thus improving the pre-heating effect and production efficiency. At the same time, the material layer is even and stable. Lower less and over-burning rate, higher finished product quality, better market feedback effect.
3. Excellent parts, environmental operation.
The rotary kiln's work motivation uses frequency converter control and operation, besides, it adopts fully negative pressure production, smooth airflow, stable operation, safety and reliable, which avoids no-load operation phenomenon. In addition, our company's rotary kiln introduces pulse bag filter dust removing, thus decreasing the dust, and improving the operating environment. More environmentally protective operation.Horizontal Cement Rotary Kiln for Cement Plant

5. Principle of Energy Saving Limestone Calcination Process Production Line
Qualified limestone is stored in the silo, the upper and lower level gages control feeding amount, and then through the tremie pipe, limestone is evenly distributed into every chamber of the preheater.
Limestone in the preheater is heated by 1150 degrees Celsius to 900 degrees Celsius, about 30% is decomposed, hydraulic pusher push them into the rotary kiln, the limestone in the rotary kiln is roasting and decomposed into CaO and CO2. 

After decomposition, generated lime enters into the cooler, in the cooler blowing cool air cool the lime to below 100 degrees Celsius and is discharged. 600 degrees Celsius hot air through heat exchange enters into the kiln and with gas fuel combination. Exhaust gas is added cool air blast and by the draught fan, enters into the bag filter, and then discharged through the exhaust fan into the chimney. By vibrating feeder, chain bucket conveyor, bucket elevator, belt conveyor, the lime discharged from the cooler enters into the lime reservoir. According to the user's needs to determine whether proceed screening processes. 

In the lime roasting system, in accordance with output, the preheater is divided into several preheaters, every preheater is matched with a set of hydraulic pusher device, and matched with automated control systems, which can send related datas into central control room's PLC control platform to realize centralized control. This system has high degree of automation and can achieve single point controlled to make the production process more convenient.
