Mining belt conveyor industry trends in May 2025: technological innovation drives efficient and intelligent development
I. Technological Innovation: Patent Strategy Driving Industry Upgrades
1. Optimization of Anti-Deviation Technology: Enhancing Conveyor Stability
Technical Breakthrough:
The "Anti-Deviation Belt Conveyor for Mining" (Patent No. CN119929434A), jointly developed by Wuxi Institute of Technology and Changzhou Sanheng Automation Technology, was officially published on May 9.
Technical Highlights:
Incorporates a slider–push plate buffer structure that effectively absorbs operational impact forces, reduces belt wear and deviation, and enhances stability during long-distance transport—particularly under high-load conditions.
2. Automated Cleaning Technology: Bionic Robot Supporting Efficient Operations
Technical Breakthrough:
Pingdingshan Tian’an Coal Mining, in collaboration with China University of Mining and Technology, introduced a “Scraper-Lift Bionic Robot for Spillage Cleaning.”
Technical Highlights:
Simulates crab-like material-handling actions by integrating a scraping and lifting mechanism to automate the removal of spilled material along conveyor lines, reducing manual intervention and improving underground operational efficiency.
3. Intelligent De-Icing Technology: Ensuring Stable Operation in Extreme Cold
Technical Breakthrough:
Ningxia Tiandi Northwest Coal Machinery has applied for a “Belt Conveyor De-Icing Device” (Patent No. CN119929439A).
Technical Highlights:
Combines ultrasonic detection with a mechanical de-icing mechanism to monitor and clear ice buildup in real-time on the conveyor belt surface, ensuring continuous and reliable operation in low-temperature environments.
4. Narrow-Space Adaptation: Cart-Type Tensioning Device Enhancing Safety
Technical Breakthrough:
Xi’an Heavy Equipment Chenghe Coal Mine Machinery developed a “Cart-Type Tensioning Device” (Patent No. CN222248781U).
Technical Highlights:
Specially designed for narrow underground roadways, this system uses a worm-gear drum with manual adjustment to maintain stable belt tension. It is well-suited for operations in confined spaces, improving transport safety in coal mines.
II. Industry Trends: Parallel Development of Intelligence and Environmental Sustainability
1. Intelligent Upgrades: Remote Monitoring + Permanent Magnet Drive
Application Case:
Jinneng Holding Equipment Group’s Jinding Company continues to advance the adoption of permanent magnet motor drives, remote visual control, and intelligent fault prediction systems.
Industry Impact:
Enables real-time data monitoring and operational optimization of conveyor systems, significantly reducing operation and maintenance costs.
2. Environmental Technologies: Dust Control Supporting Green Mining
Technical Breakthrough:
Guizhou Lufa has developed a negative-pressure dust-collecting belt conveyor (Patent No. CN222373857U).
Technical Highlights:
Features high-efficiency dust removal technology to reduce airborne particle emissions during transport, meeting the requirements of green mine development standards.
3. Market Demand: Clear Trend Toward Large-Scale and High-Efficiency Systems
Market Case:
Yangquan Coal Industry Group’s Boli Coal Mine recently issued a tender for a belt conveyor in a gangue haulage roadway with a transport capacity of 700 tons/hour and a horizontal distance exceeding 2.2 km.
Technical Highlights:
Utilizes variable frequency drive and automatic tensioning technology, reflecting growing market demand for large-capacity, long-distance conveyor equipment.
