What Is The Reason For The Jump Of Rotary Kiln

2. The parts on rotary kiln body are worn and the whole kiln sinks. The rotary kiln is a large-load continuous operation equipment. After long-term operation, the components such as the rolling ring, the support roller and the backing pad are worn a lot, and the uneven foundation settlement causes the overall kiln body to fall, so that the tooth top clearance becomes smaller and causes vibration.
