When the belt conveyor is running, its driving device, driving roller, reversing roller and idler group will make abnormal noise when they are abnormal. The equipment fault can be judged according to the abnormal noise.
1. Noise when the idler is seriously eccentric
During the operation of the belt conveyor, abnormal noise often occurs to the idler, accompanied by periodic vibration, especially to the return idler. Because of its large length, self weight, and high noise, there are two main reasons for the noise. One is that the wall thickness of the seamless steel pipe used to manufacture the idler is uneven, and the centrifugal force generated is large. The other is that the deviation between the center of the bearing holes at both ends and the center of the outer circle is large during processing, If the centrifugal force is too large, the bearing can be used continuously without damage and noise.
2. Noise when two shafts of the coupling are not concentric
Abnormal noise from the coupling between the motor and the reducer at the high speed end of the drive device or the coupling with the brake wheel. This noise is also accompanied by vibration with the same rotating frequency as the motor. When this noise occurs, the position of the motor reducer should be adjusted in time to avoid the fracture of the input shaft of the reducer.
3. Abnormal noise of reversing drum and driving drum
The turning drum and drive drum make little noise during normal operation. In case of abnormal noise, the bearing is generally damaged and the bearing seat makes a gurgling noise. At this time, the bearing should be replaced.
On October 30, Li Zhenbo, General Manager of Information Technology at Shandong China Coal Group and General Manager of Zhongyun Group, was invited to deliver a keynote presentation at an activity organized by the Teaching and Research Group of the Shandong Province Technical and Vocational Schools Admissions and Employment (Industry-Education Integration) Center. The event brought together 23 technical and vocational schools across the province and focused on innovative integration of artificial intelligence with technical and vocational education, sharing practical achievements from the front lines of industry and jointly exploring new approaches to cultivating versatile digital-skills professionals through school-enterprise collaboration.
Recently, the Zhongmei Zhiren AI system, independently developed by the Intelligent Research Institute of Shandong China Coal Group, has continued to evolve and improve. Drawing on core technologies including large language models (LLMs), retrieval-augmented generation (RAG), AI agent workflow orchestration, multimodal vision, and audio and video generation, it is building a dedicated end-to-end AI platform for China’s industrial and mining supplies sector. The platform uses independently controllable AI technology to support the digital transformation of domestic and international trade and foster new quality productive forces.
Recently, three sets of software independently developed by Shandong China Coal Industry & Mining Supplies Group Co., Ltd. have successfully passed the review of the National Copyright Administration and obtained the Computer Software Copyright Registration Certificates. The three certified achievements are all built-in agent modules of the China Coal Zhiren AI System, namely: China Coal Zhiqing Image Management Tool V1.0, China Coal Construction Machinery Foreign Trade Independent Website System V1.0, and China Coal Mining Machinery Foreign Trade Independent Website System V1.0. This marks the continuous expansion of the ecological layout of the China Coal Zhiren AI System and the further consolidation of self-developed technical barriers.
Shandong China Coal Mining Support Equipment Co., Ltd. was founded in the 1990s with more than 1100 employees. It now has 53 professional companies, 3 Hong Kong companies, 1 British Cayman company and 1 American company. It is a large diversified industrial group integrating intelligent equipment manufacturing, e-commerce, software research and development and intelligent logistics, which is cultivated and supported by the Ministry of industry and information technology, the Ministry of Commerce, the development and Reform Commission, Shandong Province and Jining City.
