Description of Lime Rotary Kiln (Active Lime Calcining Equipment):
Active lime can be widely used in a wide range of industries, such
as steel, alumina, magnesium, calcium carbide, papermaking field,
etc. As an important auxiliary material, active lime can not only
help to improve the quality and output of steel, but also reduce
the consumption and costs as well as ensure stable operation of
steel industry. Considering the potential economic benefits of
active lime for various fields, CITIC HMC Co., Ltd has developed
the 1000t/d lime rotary kiln for customers worldwide. And now this
machine has been well received by clients from Vietnam, Russia,
Central Africa, and more.
Advantages of Lime Rotary Kiln (Active Lime Calcining Equipment):
1. High productivity makes it possible for our lime rotary kiln to
be used in large active lime production line.
2. Open-type calcining rotary kiln has a simple structure, and can
discharge sulfurous gases timely, which makes it quite suitable for
steelmaking.
3. It is capable of calcining 10 to 50mm fine limestone directly.
4. Vertical preheater has been equipped at the end of the kiln to
make full use of high-temperature gases generated during calcining.
It can preheat limestone to the decomposition conditions. In this
way, it helps not only to increase the output, but also to decrease
the heat consumption.
5. The equipped vertical cooler at the head of the kiln can help
cool the high-temperature limestone, as well as make it convenient
to convey and store. Besides, it can effectively increase the
temperature inside the kiln, thus reducing the fuel consumption.
6. Waste gases, discharged from the vertical preheater, have a
temperature ranging from 280°C to 350°C, and their dust content is
about 20g/Nm3. So it is easy to deal with these gases according to
the requirements of environmental protection.
7. With stable performance, our active lime calcining equipment is
also suitable for mine exploitation
