Industrial Lime Production Line Of Rotary Kiln Lime Calcination
Furnace Lime Burner
Introduction of Rotary Lime Kiln
The rotary kiln produced has advanced structure. It can effectively
improve preheating effect with its low resistance vertical
preheater. After the material is preheated, the feeding
decomposition rate can reach 20%-25%, thus can directly make use of
10-15mm fine fraction materials. The reliable airtight two-ends
combination squama make the air leakage factor under 10%. The usage
of compound refractory reduces radiation loss.Rotary kiln belongs
to building material equipment, which can be divided into cement
kiln,metallurgy chemical kiln and lime kiln according to different
materials.
Working Process of Lime Rotary Kiln
Limestone and fuel into the lime kiln (if fuel gas pipelines,and
the burner into) began to decompose after preheating to 850
degrees,1200 degrees to complete calcination,after cooling
discharged out of the kiln.
Quick lime production is completed. Different kiln form have
different preheating,calcination,cooling and discharging mode.
But there are several process principle is the same:
high quality raw material,lime quality is good;
Fuel high calorific value,less number of consumption;
Particle size of limestone and the calcination time is proportional
to the;
Quick lime activity degree and calcination time,calcination
temperature is inversely proportional to.
Advantages of Lime Rotary Kiln
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.
