What are the reasons for belt deviation of belt conveyor?

1. Belt deviation caused by installation
The installation quality of the belt conveyor has the greatest impact on the belt deviation. The belt deviation caused by the installation error is the most difficult to deal with. The installation error is mainly:
a. The conveyor belt joint is not straight. The tension on both sides of the belt is uneven, and the belt always deviates to the side with high tension.
b. The rack is skewed. The rack deflection includes the deflection of the center line of the rack and the high and low tilt of both sides of the rack, both of which can cause serious deflection and are difficult to adjust.
c. The pressure of rubber plates on both sides of the guide chute is uneven. Due to the uneven pressure of the rubber plate, the running resistance on both sides of the belt is inconsistent, resulting in belt deviation.
2. Belt deviation caused by running
a. Deviation caused by sticking of roller and idler. After the belt conveyor has been running for a period of time, due to the certain viscosity of mineral aggregate, some mineral powder will stick to the drum and idler, making the drum or idler local diameter larger, causing uneven tension on both sides of the belt, resulting in belt deviation.
b. Deflection caused by belt looseness. After the adjusted belt runs for a period of time, due to deformation or aging caused by belt stretching, the tension of the belt will decrease, resulting in belt relaxation and belt deviation.
c. Deviation caused by uneven mineral aggregate distribution. If the belt does not deflect when idling, it will deflect when running under heavy load, indicating that the mineral aggregate is unevenly distributed on both sides of the belt. The uneven distribution of mineral aggregate is mainly caused by the incorrect falling direction and position of mineral aggregate. If the mineral aggregate deviates to the left, the belt deviates to the right, and vice versa.
d. Deviation caused by vibration during operation. The mechanical vibration of the belt conveyor during operation is inevitable. The faster the belt is running, the greater the vibration, and the greater the belt deviation. In the belt conveyor, the vibration caused by the radial runout of the idler has the greatest impact on the belt deviation.
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.
