Analyze the Casting Materials of Cylinder Rotary Kiln - Delhi

According to the exterior, the rotary kilns can be divided into diameter changes rotary kiln and size rotary kiln, into cement rotary kiln, ceramsite sand rotary kiln, soil rotary kiln and lime rotary kiln based on the purposes, into gas powered rotary kiln, coal-fired rotary kiln and mixed fuel rotary kiln depending on the different effects.

A cyliner rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object. It is made up of a strong reinforced steel outer shell that is coated with a heat-resistant inner lining, support rollers and a drive gear to keep the contents in a continuous rotating motion and internal heat exchangers capable of producing temperatures well over 2732 degrees Fahrenheit (1500 degrees Celsius).




Notes for the Casting Materials of cylinder rotary kiln:

The casting material of the rotating kiln will be affected by the principle of thermal expansion and cold contraction. So, when choosing the casting materials, should taking the character of resistance to high temperature into account.

The life of casting material of the opening of rotating kiln is very short. They usually will fall down every several months. This problem may cause the rotary kiln have to be stopped to check and repair, at the same time this may effect the common work of the machines.

In order to increase the using life of casting material, we should decrease the temperature different of the casting material. This can reduce the damage to the casting materials because of the principle of thermal expansion and cold contraction.In order to decrease the temperature difference, we can increase the casting length of the opening of the rotary kiln. This can enlarge the heating area and decrease the temperature difference at the same time.
