Lime Rotary Kiln Technology
Lime rotary kiln is also called rolling kiln, belongs to building material equipment. It is the main equipment for sintering cement clinker in cement production plant, and can be divided into cement rotary kiln, metallurgical chemistry kiln, and lime rotary kiln according to different materials.
Lime rotary kiln is the main metallurgical and chemical equipment that is used to produce fibrous agalmatolite materials, with industry-leading product performance and reliable energy-saving technology level. The simple and solid structure, the convenient operation and maintenance, and the continuous production of large capacity have made the lime rotary kiln a place as the most important equipment in cement and other building materials enterprises.
Working Principle of Lime Rotary Kiln
The working principle of lime rotary kiln is very simple, that is, the fuel is burned on the grate at the lower part of the kiln, and the material is moved to the upper part of the kiln along the cylinder body which is the rotating part. In this way, the material can be heated up to a high temperature, and the chemical changes, such as the release of carbon dioxide, can be achieved.
The main components of the lime rotary kiln include the kiln head, the kiln shell, the reducer, the measuring device and the support roller. The kiln head and the kiln shell are welded together, and the support roller is laid around the kiln shell, and the guide device is set between the roller and the kiln, so that the entire kiln body can be turned when operating. The kiln shell is equipped with an inlet pipe at the upper part and an outlet pipe at the lower part.
The reducer installed on the upper part of the kiln is used as the motor, and the motor is connected to the kiln head through an axle, and then the reducer drives the kiln shell to rotate, so that the material inside the rotary kiln can be changed.
Manufacturing Process of Lime Rotary Kiln
The manufacturing process of the lime rotary kiln is complicated, but simply it can be divided into five stages.
1. Foundation Construction: In this stage, the foundation and structure of the lime rotary kiln will be constructed. This includes the preparation of the foundation pits, the backfill and excavation, the compaction and drainage of the foundation and the grouting of the foundation and the structure.
2. Installation of Main Components: This is done after the foundation and structure are complete. The main components of the lime rotary kiln, including the walking wheel, fire grate, rotary kiln shell and kiln head, are installed and adjusted.
3. Rotary Kiln Pre-heating: This is to preheat the main components of the kiln, such as the walking wheel, fire grate and rotary kiln shell, for a period of time.
4. Configuration of Auxiliary Equipment: When the main components of the rotary kiln have been heated, it is then time to configure other accessories of the kiln, such as the monitoring system, kiln body seal and fan.
5. Commissioning: The last step is to conduct tests to ensure that the kiln is running smoothly, and to adjust the related parameters to make the rotary kiln of better quality.
Lime rotary kiln is an important equipment in the technology to produce cement and some kinds of material production. It works by burning fuel in the lower part and then heating up the material inside the kiln with its rotating movement. The complex manufacturing process ensures the product’s safety, reliability, and energy-saving level. It is the ideal choice for producing materials in building material technology.
