Rotary Calcination Kiln
Brief Introduction of Rotary Calcination Kiln:
Rotary Calcination kiln belongs to building material equipment, which can be divided into cement calcination kiln, metallurgy chemical calcination kiln and lime calcination kiln according to different materials. Cement calcination kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical calcination kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary calcination kiln is used for calcimine of high aluminum vandal ochre in refractory material industry, calcimine of calotte and aluminum hydroxide in aluminum manufacturer, claiming of chrome sand ore and chrome powder ore in chemical plant.
Features of Rotary Calcination Kiln:
1. Low pressure drop pre heaters.
2. Raw mill equipped with High efficiency separator.
3. Raw Meal blending in CFC silo.
4. Pre calciner suitable to work with alternative fuels.
5. Inlet & discharge fitted with efficient seals.
6. Benchmark cooler design.
7. Low Fuel Consumption.
Application of Rotary Calcination Kiln:
The Rotary calcination kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary calcination kilns include:
Cement
Lime
Refractories
Metakaolin
Titanium dioxide
Alumina
Vermiculite
Iron ore pellets
They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
Working Principle of Rotary Calcination Kiln:
Through the technical renovations, the rotary calcination kiln calcining system equipment made has adopted the advanced hydraulic thrust roller device, the high measuring precession plunger pump, the variable speed adjusted valve, the contact graphite block sealing device and the other national advanced technologies. In order to raise up automation degree, the industrial TV has been used at the kiln head for monitoring of kiln,With the use of these new of these new technologies, it is direct in vision, convenient in operation and reliable in use. Therefore, the thermal condition can be stabilized and the running rate of equipment can be raised. Compared to same sized equipment, its running rate has been raised 10% up, production has been increased 5-10% and heat consumption has been reduced 15% down.
