How to Improve the Service Life of Cement Kilns

In today's society, low-carbon economy is increasingly being respected, the status of cement kiln is more and more important. Cement rotary kiln is the main equipment of cement clinker dry and wet production line. It is widely used in cement, metallurgy and chemical industry. How to effectively protect the cement rotary kiln, improve its service life is the key.

1.It is the key to open and stop for cement rotary kiln , heating less than 60 ℃ per hour, more than 300 ℃ insulation control.
Because of the large thermal expansion coefficient of cement rotary kiln, the expansion rate of 1000 ℃ is about 1-1.2%. During the drying process, especially in the area of brick surface temperature of 300-1000 ℃, the heating rate must be less than 60 ℃ / H. This is theoretically very clear, in the implementation there is a certain degree of difficulty, it is recommended to use dual oil flow gun. At the beginning, the kiln is oiled. After a certain temperature, it is mixed with kerosene to save oil. After the temperature of the brick surface exceeds 1000 ℃ (in the case of flame, the brick surface is dark red), it is better to control the heating process. .
2. Equipment is the foundation
The long-term safe operation of the equipment is the basis for strict implementation of the ignition system and the kiln system. If the equipment state is not good, then every month should have several times or even a dozen times of stopping kiln, and each stop kiln should use 20 hours to bake kiln, whether time or cost cannot afford, so the equipment is the foundation.

4. Stability is a prerequisite
Hang up and maintain a good kiln to extend the life of the rotary kiln is essential to protect the kiln skin is the premise of the stability of the thermal system, because the kiln each time the larger temperature fluctuations will cause the kiln skin to varying degrees hurt.

5. Management is guaranteed
Follow the technical laws, do a good job in all aspects of the management process is to use good alkaline brick, to extend the life of rotary kiln guarantee.

Repair and maintenance of the cement kilns is essential, so it is imperative that the rotary kiln be operated by hand, and that the system is properly trained before the induction of the operator, in order to ensure the normal operation of our rotary kiln equipment and to extend the equipment of life.
