[0002] The rotary kiln is mainly composed of a kiln head, a kiln body, a kiln tail and a support frame. The kiln head, the kiln body and the kiln tail form the core of the rotary kiln, completing production tasks such as feeding, calcining and discharging. The kiln body is the main body of the rotary kiln, usually 30-150 meters long, cylindrical, with 3-5 rollers in the middle. The roller part is used to support the kiln body and limit the movement of the kiln body to prevent it from falling during rotation. The existing rollers are directly fixed on the outer wall of the kiln body. During long-term high-temperature operation, deformation and wear will occur. The deformation of the kiln body is uncontrollable, so the deformation of the roller part is also random. During long-term operation, the shape of the roller gradually changes, causing the kiln body to vibrate, causing irreversible mechanical damage. Utility Model Content
