about rotary kiln
The rotary kiln is a large-scale high-temperature calcination equipment, widely used in industries such as cement, metallurgy, chemical engineering, environmental protection and new materials. Its core structure is an inclined and rotating cylinder. Materials undergo high-temperature heating, physical or chemical reactions inside the kiln, ultimately achieving the decomposition, calcination, reduction or drying of minerals.
Rotary kilns have become core equipment in modern industrial production due to their outstanding thermal efficiency, stable calcination performance and wide material adaptability. Its unique rotating cylinder design ensures uniform heating of materials. Combined with an intelligent temperature control system, it can achieve precise calcination, increasing thermal efficiency by more than 30% and reducing energy consumption by 20%.

Common problems of rotary kilns
Mainly due to long-term high-temperature operation, uneven heating, and local overheating of the cylinder. The installation accuracy of the kiln body support device is insufficient. The material load is uneven.
To solve this problem, it is necessary to strictly control the temperature inside the kiln to avoid local overheating. Regular inspection and treatment of uneven settlement; Readjust the installation accuracy of the support device; Reasonably control the material load and feed evenly.
The contact stress between the idler wheels and the wheel belt is large. If the lubrication is not in place, it will increase the friction and lead to wear. Another possibility is that the centerline of the kiln body is not straight, resulting in uneven force distribution.
To solve this problem, the first step is to choose a reliable equipment company. The rotary kiln designed by Chunlei Machinery features a reasonable structure and size of the supporting rollers and wheel belts, reducing contact stress. Meanwhile, the surfaces of the idler rollers and wheel belts are finely processed to ensure that the surface roughness meets strict requirements.
On the other hand, customers should also strengthen lubrication management and add and replace lubricating oil regularly. Regularly inspect and adjust the centerline of the kiln body to ensure its straightness.
