In May 2025, the mine belt conveyor industry achieved remarkable progress in technological innovation, standard refinement, and market expansion. Intensive industry exchanges, corporate collaborations, and technological breakthroughs emerged as core themes. Below is a summary of key developments:

I. Industry Events: Technological Exchange and Strategic Deployment

From May 17 to 20, the 2025 General Meeting of Members and the 11th Fourth Council Meeting of the Belt Conveyor Branch of the China Heavy Machinery Industry Association were successfully held in Yuanping City, Shanxi Province. Themed "Conveying Hope, Innovating the Future," the event attracted nearly 300 industry experts and corporate representatives.

• Technological Innovation Highlights:

• Yin Renqiang, Chief Engineer of Shanxi Dongchang Industrial Co., Ltd., shared the company's technological breakthroughs in belt conveyors, including high-strength conveyor belts and intelligent monitoring systems.

• Qingdao Brilliant Rubber & Plastic Co., Ltd. proposed the concept of "low-carbon, intelligent bulk material conveying services," showcasing technologies for low-friction, long-life conveyor belts to help mining enterprises reduce costs and increase efficiency.

• Dalian Keduo Fluid Drive Technology Co., Ltd. promoted its "valve-controlled, delayed-filling torque-limiting hydraulic coupler," enhancing conveyor stability through optimized starting torque and overload protection.

• Policy and Strategic Insights:

• Wang Jisheng, Honorary President of the China Heavy Machinery Industry Association, emphasized the need for the industry to align with national strategies, strengthen AI integration, expand international markets, and cultivate "specialized, refined, distinctive, and innovative" enterprises.

• Liang Dong, a representative from the International Copper Association, analyzed trends in the copper industry, offering new perspectives on lightweight materials and enhanced conductivity for conveyor belts.

II. Technological Breakthroughs: Air-Suspended Conveyors and Intelligent Management Platforms Lead Industry Upgrades

1. Jinchuan Group’s First Air-Suspended Belt Conveyor Commissioned
   In May, Jinchuan Group and Zhangsheng (Hangzhou) Machinery Equipment Co., Ltd. jointly developed an air-suspended belt conveyor, successfully deployed at the Smelting Branch No. 1 of Tonggui Company. Leveraging aerodynamics, the system forms an air film to support belt operation, eliminating mechanical friction risks such as slippage and breakage. Its fully enclosed design reduces dust pollution. Jinchuan plans to expand this technology across its operations to advance mining automation and intelligence.

2. Shenyang Design Institute’s Smart Mining Technologies Debut at International Exhibition
   In April, the Shenyang Design Institute unveiled its "ultra-long-distance belt conveyor reversible conveying system" at the 3rd China (Xi’an) International Mining Equipment Exhibition, achieving 9,000-meter单机长度 (single-machine length) and stable operation at -40°C. Applied to the Shengli No. 1 Open-Pit Coal Mine’s coal conveyance to a power plant, the system also features an "open-pit mine intelligent integrated management platform" integrating BIM, GIS, and digital twin technologies. This platform enables full-chain digital management, boosting production efficiency by 25% and reducing safety incidents by 90%.

III. Standards and Safety: Policy-Driven Industry Standardization

1. Industry Standard Enhancements
   In 2025, the state strengthened supervision of the conveyor industry, issuing standards such as Technical Conditions for Belt Conveyors and Safety Specifications for Belt Conveyors. These standards specify requirements for equipment energy consumption, emissions, and safety design. For example, they mandate synchronized power-on and power-off for main and control circuits to prevent accidental restarts.

2. Safety Accident Alerts and Prevention
   A recent belt conveyor entanglement accident at Caoduogou Coal Industry in Zuoyun County, Datong, Shanxi, underscored the importance of safety oversight. Industry experts recommend:

• Establishing regular equipment inspection regimes, focusing on idler wear and belt aging.

• Deploying intelligent monitoring systems to track belt tension and misalignment in real time, enabling predictive maintenance.

• Enhancing employee safety training and emergency response capabilities.

IV. Market Dynamics: Active Tendering and "Belt and Road" Expansion

1. Major Tender Projects Released

• On May 7, Hebi Coal & Electricity Co., Ltd. issued a 2025 equipment procurement tender for belt conveyors, mine hoists, and other machinery, requiring bidders to demonstrate similar project experience in the past three years.

• On May 16, Wukuang Mining Anhui Development Co., Ltd. launched a tender for four belt conveyors, demanding delivery to the Laixin Iron Mine project site in Shandong within 45 days of contract signing.

2. International Market Expansion
   The Shenyang Design Institute has signed cooperation agreements with Pakistan, Indonesia, and other countries. Its design for the Thar Coal Block I Open-Pit Mine in Pakistan has become a "Belt and Road" benchmark project. Additionally, industry players are enhancing global competitiveness by participating in international standard-setting.

V. Future Outlook: Green and Intelligent Technologies Dominate Trends

As China advances its "dual carbon" goals, the industry will accelerate its transition toward green and low-carbon operations. Key priorities include:

• Energy-Efficient Technologies: Developing low-resistance idlers and permanent magnet direct-drive motors to reduce energy consumption.

• Intelligent O&M Systems: Integrating IoT and big data for remote equipment monitoring and predictive maintenance.

• Material Innovation: Promoting recyclable conveyor belts and lightweight steel structures to curb resource consumption.

In May 2025, the mine belt conveyor industry made strides in technological innovation, standard refinement, and market expansion. Moving forward, the sector will focus on green and intelligent development to drive safe, efficient, and sustainable mining operations.
