Rotary kiln is the main equipment for calcining cement clinker
and it can be used widely for cement industry, metallurgy industry,
chemical industry, etc. The rotary kiln is composed of the shell,
the supporting device, the supporting device with thrust roller,
the driving device, the movable kiln head, the sealing device at
kiln tail, the combustion device, etc. It has the simple structure
and reliable operation, at the same the production process of the
rotary kiln can be controlled easily.
Through the technical renovations, the rotary 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, the simulation phosphor screen
has been used for display of process flow; the infrared scanning
system has been adopted for calcining zone to directly reflect the
burning conditions on the computer. 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
*0% up, production has been increased ***0% and heat consumption
has been reduced *5% down.
Rotary kiln belongs to building material
equipment, which can be divided into cement kiln, metallurgy
chemical kiln and lime kiln according to different materials.
Cement kiln is used for making of cement
clinker and there are dry and wet methods to make cement.
Metallurgy chemical kiln is used for magnetic roasting of iron ore
and oxidizing roasting of chrome and nickel in the steel factory,
baking high-alumina mine in the refractory material factory; baking
chamotte and alumina in the aluminum factory and baking chrome ore
and chrome powder in the chemical plant
