The Rotary Kiln, also called the kiln dryer, cement rotary kiln and lime rotary kiln, is the key equipment in cement production, which is mainly composed of kiln body, transmission device, supporting device, block wheel device, kiln head sealing device, kiln tail sealing device, kiln head hood, etc.
The Rotary Kiln, also called the kiln dryer, cement rotary kiln and lime rotary kiln, is a type of rotating calcining kiln used in the industries of construction materials, metallurgy, chemical engineering and environmental protection. There are three types of rotary kilns according to the material treatment modes: cement kiln, metallurgy chemical engineering and lime kiln.
Rotary Kiln is the key equipment in cement production, which is mainly composed of kiln body, transmission device, supporting device, block wheel device, kiln head sealing device, kiln tail sealing device, kiln head hood, etc.
Rotary kiln is the cylinder shape machine with a certain inclination of 3 ~ 3.5%. With the help of kiln rotation, the mix and reaction of materials in rotary kiln will be promoted. The coal combustion of kiln head will produce a lot of heat, which will be transferred to material in the flame radiation, heat convection and brick kiln conduction ways. The moving of material relies on the inclination and rotation of the kiln.
The rotary kiln's application standard for coal
The application standard for coal is suitable for the large and medium size cement plants to burn coal and also can be regarded as the basis of the equipment technical transformation and design for the cement plants. This standard can work as the evaluating guideline for the coal resources in the ore field and the coal exploitation and processing project.
Zhengzhou Lanyu Mechanical has been devoted to the production of lime rotary kiln cement rotary kiln for thirty years and we own the professional and advanced technology of manufacturing cement rotary with the complete production system.
