Latest company news about Composition structure and working principle of rotary kiln equipment

Rotary kiln is just another name for rotary kiln equipment. Rotary kiln can burn many different materials and is a common roasting equipment. And now, in order to control the quality of finished clinker, automatic control devices are used, so that a large amount of raw meal can be processed with lower energy consumption, and the quality of equipment calcination can also be improved. To achieve the characteristics of high yield and low energy, the equipment can strengthen energy conservation while firing high-quality clinker. The addition of an automatic control device can reduce the labor cost of the rotary kiln equipment, so what is the structure and working principle of the rotary kiln equipment. Consider the following analysis:

1. There are chemical and physical reactions inside the rotary kiln, and the calcination stage is divided into three stages, preheating stage, calcination stage and cooling stage. When calcining limestone, the heat between the material and the calcining belt in the area of ​​the rotary kiln exchanges back and forth, so that the moisture of the raw material is evaporated. Under the condition of uneven heating, the volume expands and the ultimate compressive strength decreases. When the internal temperature reaches 700 degrees Celsius, it enters the calcining zone.

 

2.The calcining zone is in the middle of the rotary kiln. When the material enters the area, the fuel starts to burn with the help of the blower. A lot of heat can be released, so the temperature in the kiln will slowly rise when the temperature reaches a certain range. At this time, the temperature control process must be carried out. For example, the decomposition rate of limestone and the gas generated in this case will be relatively large, which is beneficial to the calcination of raw meal into clinker. The generated gas is discharged under the drive of the airflow, and the clinker begins to enter the cooling zone at this time

 

3. The cooling zone is in the lower part of the kiln body of the rotary kiln. At this time, the residual clinker will not be decomposed in this area. At the same time, the calcined material can be cooled. The relative position of each area is also relatively stable. It cannot be separated randomly, and must be operated according to changes in raw materials and fuel conditions. After cooling inside the kiln body, the materials can be better utilized. These are just simple introductions to the composition and principle of the rotary kiln. If you are interested in purchasing, you can go to a manufacturer that can produce metallurgical rotary kiln equipment to increase users' knowledge.
