China’s Largest Single Aggregates Mine Now Operational – 55 Million TPY, Smart Control, and a Blueprint for Modern Quarrying
Why a 55‑million‑tonne‑per‑year aggregates mine with full‑process intelligent control is setting a new benchmark for large‑scale quarry operations
On October 25, 2025, the Chongwangling mine project in Yunfu, Guangdong Province – owned and operated by China Power Construction’s Yunfu New Materials subsidiary – successfully completed its first trial production run. With total recoverable resources of 1.257 billion tonnes and a design capacity of 55 million tonnes per year, the mine is the largest single‑site building materials mine in South China and ranks second in reserves nationwide. The project represents an investment of nearly RMB 20 billion, including a 21‑kilometre overland conveyor system with 15.5 kilometres of tunnel and seven 5,000‑tonne‑class Yangtze River berths. For quarry operators, mining companies, and aggregate producers worldwide, this project demonstrates how advanced crushing technology, integrated logistics, and intelligent process control can work together to deliver consistent, high‑quality aggregate production at an unprecedented scale. At OCP Mechanical Company, with over 40 years of manufacturing experience, we supply a comprehensive range of crushing and screening equipment – including PE Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines – designed to support large‑scale aggregate operations, all at factory‑direct prices.
A resource base built for decades of sustained production
The Chongwangling mine sits on a world‑class resource base. Total geological resources exceed 470 million cubic metres, with recoverable reserves of 463.76 million cubic metres – equivalent to 1.257 billion tonnes. The ore body consists of high‑quality construction granite and metamorphic sandstone, with all key indicators meeting China’s national Class I construction aggregate standards. The mine is permitted for a 25‑year service life, with an annual extraction capacity of 20 million cubic metres per year. This combination of scale, quality, and long‑term reserve security provides a stable foundation for the project’s 55‑million‑tonne annual output, positioning it as a critical supply base for infrastructure development across the Greater Bay Area and the broader Yangtze River Delta region. For equipment buyers, the Chongwangling project demonstrates that large‑scale aggregate operations require equipment that can sustain continuous, high‑throughput production over decades – not just years. OCP Mechanical’s PE Series jaw crushers and HST Series cone crushers are engineered with heavy‑duty construction, long wear life, and low maintenance requirements, ensuring reliable performance over the long haul. All product specifications, including capacity and power ratings, are continuously updated; for the latest parameters, please consult our online customer service.
Three‑stage crushing with rod‑mill sand making – a proven process for premium aggregates
The Chongwangling project employs an advanced production process that combines three‑stage crushing, rod‑mill sand making, and vertical‑shaft shaping in a dry‑wet integrated flowsheet. The three‑stage crushing circuit includes primary gyratory or jaw crushing, secondary cone crushing, and tertiary cone or impact crushing, followed by rod‑mill sand making and VSI shaping to produce premium manufactured sand and high‑grade aggregates. This process enables the plant to produce a full range of finished products, from 0–5 mm manufactured sand to multiple aggregate sizes, all with low fines content, rounded particle shape, and precise gradation. The dry‑wet integrated design also provides operational flexibility, allowing the plant to adapt to different feed conditions and product specifications. For quarry operators, this process demonstrates that modern aggregate production requires a well‑engineered combination of crushing, screening, and sand making equipment. OCP Mechanical offers complete processing solutions that can be configured to match this three‑stage approach, with PE Series jaw crushers for primary reduction, HST Series cone crushers for secondary and tertiary crushing, and VSI 6X sand making machines for manufactured sand production. Prices are for reference only and are subject to change based on configuration and market conditions.
21 kilometres of intelligent conveying – logistics that match the scale of production
At the heart of the Chongwangling project’s logistics system is a 21‑kilometre overland conveyor system, including 15.5 kilometres of tunnel, that connects the mine to the Yangtze River port. The conveyor system is designed to operate at 10,500 tonnes per hour at a belt speed of 5.6 metres per second – a capacity that matches the mine’s 55‑million‑tonne annual output. In March 2026, the system successfully completed full‑load commissioning, demonstrating that it can sustain the required throughput for full‑scale production. The conveyor system is equipped with advanced monitoring and control systems, enabling real‑time performance tracking and predictive maintenance. This logistics capability is critical to the project’s economics, as it enables efficient, low‑cost transport of aggregates to the Greater Bay Area and other key markets. For equipment buyers, the Chongwangling project highlights the importance of integrated material handling systems in large‑scale aggregate operations. OCP Mechanical offers complete material handling solutions, including feeders, conveyors, and screening systems, designed to integrate seamlessly with crushing and sand making equipment.
Full‑process intelligent control – the benchmark for modern quarry management
The Chongwangling project is built around a full‑process intelligent control system that covers every stage of the operation – from mining and crushing to logistics and quality control. The smart mine system includes 62 3D laser scanners, 20 radar level sensors, 10 control stations, and multiple online particle size analysers, enabling real‑time monitoring of material flow, equipment performance, and product quality. Intelligent water treatment and dust monitoring systems ensure environmental compliance. This level of digital integration enables operators to track performance, identify bottlenecks, and optimise settings in real time – all from a central control platform. For quarry operators, this demonstrates that intelligent control is not just a technology upgrade; it is a fundamental requirement for achieving consistent product quality, reducing operating costs, and maintaining environmental compliance at scale. OCP Mechanical’s equipment can be integrated with modern monitoring and control systems, including load‑sensing controls and remote diagnostic capabilities, enabling operators to achieve similar levels of intelligent process management.
What the Chongwangling project means for equipment buyers worldwide
The Chongwangling project is more than a single mine – it is a demonstration of what is possible when advanced crushing technology, intelligent process control, and integrated logistics are combined at scale. For quarry operators, mining companies, and aggregate producers, the project offers several key lessons. First, large‑scale aggregate operations require heavy‑duty, high‑capacity equipment that can sustain continuous production over decades. Second, advanced processing technologies – including three‑stage crushing, rod‑mill sand making, and VSI shaping – are essential for producing the high‑quality aggregates that major infrastructure projects demand. Third, full‑process intelligent control is becoming a competitive necessity, enabling operators to achieve consistent quality, lower costs, and better environmental performance. Finally, integrated logistics systems are critical for delivering product to market efficiently. While the Chongwangling project represents a significant investment in technology and infrastructure, OCP Mechanical offers a comprehensive range of crushing and screening equipment that can help operators achieve similar performance at any scale. Our factory‑direct model ensures that you get the equipment you need at competitive prices, backed by responsive after‑sales support.
