Limestone pyrolysis equipment of lime production plant for active lime and quick lime

 

 

Introduction:

Lime rotary kiln is the key equipment for the calcination of bauxite, clinker, limestone, etc.. According to the capacity of bauxite plant, clinker or cement plant, etc., we can help you select different size of rotary kiln,which is usually from 900mm to 4000mm.
Lime rotary kiln is mainly composed of kiln shell, refractory bricks, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln.
1. Supporting device: advanced shaft structure, automatic temperature measuring device and electrical heating.
2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure.
3. Gears: single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient.
4. Kiln shell tire bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won’t hurt cylinder.
5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The sealing effect is very good.
6. Kiln head hood: including stationary type and flexible type.


Working Principle:

Material will be feed into kiln tail through chute in gas chamber. As kiln shell is inclined and it rotates slightly, material will move along round shell and will also move along shaft direction from kiln tail to kiln head. Material will be processed through pre-heat, decompose, calcined and will be feed into cooler. Fuel will be given through gas or coal burner at kiln head and will be combusted in kiln. Heat will be transferred to material by fire radiate, hot air flow, kiln brick transfer. The heat will heat and calcine material enough and make it final product.


Energy Saving Rotary Lime Kiln Pyrolysis Equipment For Active / Quick Lime Production 0Features:

1. Output of rotary kiln is high which is suitable large-scale active lime production line, meanwhile the lime rotary kiln production line with daily capacity of 2200tons has been put into operation in the world and many lime rotary kiln with daily capacity of 150-500tons has been built with good operation situation which is suitable for applying in middle or small scale lime enterprises.

2. Rotary Kiln belongs to open type calcining, the structure of kiln body is simple, airflow is unblock, the gas containing S could be exhausted in time meanwhile the S during burning is hard to adhering so the sulphur content of products is low which could meet the steel-making requirements. At the same time material will go ahead evenly inside kiln with even heating, so the quality of production is stable and crude burning rate and over-burning rate is very low thus it could calcine high activity lime for steel-making. Under the same condition, lime activity produced by rotary kiln which could be 340-380ml or even 400ml is over 30ml higher on average than that manufactured by gas kiln.

3. Rotary Kiln could directly calcine 10-50mm fine power level limestone, normally 0-30mm fine power level limestone accounting for 30-40% of total volume which couldn’t be used for other type kiln. Complying with the fineness of steel raw material, sintering gradually takes use crude lime instead of limestone, as fine limestone couldn’t be used comprehensively. Rotary kiln production line could not only use good limestone ore resources, but also meets the lime industry sustainable development policies.

4. Utilizing vertical preheater in kiln end could adequately use high temperature smoke created by calcining inside of kiln which could initially pre-break down from normal temperature preheating. This could not only largely increase output of rotary kiln, but also fully decrease heat consumption each unit product.

5. Utilizing vertical cooler in kiln head could not only cool quickly of high temperature lime and increase activity, but also it is convenient for conveying and saving. Meanwhile it could gain high temperature 2nd wind when entering into kiln, which could efficiently increase temperature inside of kiln, decrease burning consumption.

6,The temperature of smoke discharged from vertical preheater of kiln end is low, normally it is between 280-350℃, whose dust containing is about 20g/Nm3, that is really low, this could make simple and efficient follow-up smoke treatment meanwhile the gas after treated could meet the environment protection standard.

7. The most important advantage of lime produced by rotary kiln is stable. Seen from total development trend, our active lime production equipment should focus on local market. Not only for adaptability of manufacturing capacity, but also for adequately utilizing good limestone ore resources, rotary kiln both have better developing future.
