Active lime rotary kiln for lime production line
Lime Rotary Kiln Application:
Rotary kiln is a combustion device for bulk and slurry material, it is widely used in cement industry, lime industry, refractory, metallurgy industry.
According to the calcination character of limestone, lime rotary kiln is specialized design for production of active lime. This type of kiln can work with vertical preheater and vertical cooler to achievethe advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.
Lime Rotary Kiln Working Principle:
It mainly consists of kiln body, sealing device for kiln tail, main and auxiliary driving device, burning device, discharging device, speed regulation , instrument control, PLC programming, interlocking device and dust-extraction device, etc.
CaCO3 is the main ingredient of the limestone, and CaO is the main ingredient of lime. The basic principle of lime burning is to preheat materials with low temperature, quickly burn them with high temperature, utilize the perheater and the kiln to heat the limestone and compose them into CaO and CO2.,
Lime rotary kiln features and benefits:
1. Widely range of adaptability to raw and fuel materials;
2. Sturdy structure, smooth running, large capacity and good quality;
3. Energy conservation, waste gas as the second useful source, recycling economy;
4. come up to the discharging standard with low NO emissions;
5. PLC auto-control system, centralized control in productive process.
The kiln body is made of high-quality killed carbon steel or alloy steel plate and welded;
The supporting type and rollers is of ZG35CrMo and 42CrMo steel;
The sliding bearing is of non-scraping liner one with large clearance;
The driving device adopts hard-toothed reducer, flexible sheet coupling, driven by DC motor;
Hydraulic thrust roll is used;
The kiln head and rear seal is of pneumatic or scaled type;
With slow speed drive.
