Active Lime Cement Rotary Kiln And Cement Rotary Kiln Factory Price

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry.

A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated and the process of heat transfer is not very efficient.

The slurry may contain about 40% water. This takes a lot of energy to evaporate and various developments of the wet process were aimed at reducing the water content of the raw meal. An example of this is the 'filter press' (imagine a musical accordion 10-20 metres long and several metres across) - such adaptions were described as 'semi-wet' processes.

The wet process has survived for over a century because many raw materials are suited to blending as a slurry. Also, for many years, it was technically difficult to get dry powders to blend adequately.
Dry process cement rotary kilns Wet and Dry Cement Rotary Kiln

In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.

The dry process is much more thermally efficient than the wet process.

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
