High Automation Level
The lime rotary kiln is with advanced structure. Its pre-heater
with low-pressure loss can improve preheating effect efficiently.
After preheating, the resolution ratio of the lime-stones can reach
20~25% when they enter the kiln. Besides, the lime-stones, with
fine fraction about 10~15mm, can be used directly.
Waste Heat be Reused Effectively
The two sides of the reliable rotary kiln are sealed by the
combined scales, which can make the air leakage coefficient less
than 10%. Composite refractory materials should be used in order to
reduce the loss of radiant heat.
Low Energy Consumption
The filling vertical cooler, round or square, can be
zoned-ventilation, which can make the temperature of lime-stones in
the cooler at about 80°C. As a result, it is very convenient to
transport and store. It can also pre-heater the secondary air up to
the temperature above 700°C, then the waste heat can be recycled to
reduce energy consumption.
