21.42 Million TPY Gneiss Mine Now Operational – A Case Study in Large‑Scale Aggregate Processing

Why a 21.42‑million‑tonne‑per‑year gneiss mine with fully integrated crushing, screening, and sand making is setting a new benchmark for large‑scale aggregate operations in the Greater Bay Area

In July 2026, CCCC Fourth Harbor Engineering Co., Ltd. (CCCC‑FHEC) successfully commissioned the Phase II production line at the Fenghuangling gneiss mine in Yangxi County, Guangdong Province. With the crushing, screening, and sand making circuits now fully operational, the project has officially transitioned from construction to production. The mine represents a total investment of over RMB 5.4 billion, with recoverable reserves of 150.9 million cubic metres—equivalent to approximately 405 million tonnes. The project is designed for an annual mining capacity of 24.12 million tonnes, with an annual processing capacity of 21.42 million tonnes. The product range includes crushed stone aggregates, manufactured sand, and riprap, serving major infrastructure projects across the Greater Bay Area and Hainan Free Trade Port. For quarry operators, mining companies, and aggregate producers, this project demonstrates how large‑scale investment in integrated processing infrastructure can deliver consistent, high‑quality aggregate supply for regional development. 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 operations of this scale, all at factory‑direct prices.

A resource‑backed operation built for long‑term supply

The Fenghuangling project is built on a substantial and high‑quality resource base. The mine is located in Xitou Town, Yangxi County, with recoverable reserves of 150.9 million cubic metres (approximately 405 million tonnes). The project is designed for an annual mining capacity of 24.12 million tonnes and an annual processing capacity of 21.42 million tonnes. The mine produces crushed stone aggregates, manufactured sand, and riprap, supplying strategic infrastructure projects including the Greater Bay Area and Hainan Free Trade Port. To support product logistics, the project includes the Fengtou Port berths F3‑F5 at Yangjiang Port, with a total investment of RMB 2.57 billion. The three 50,000‑tonne specialised berths are designed for an annual throughput of 50 million tonnes and are scheduled for completion in the first half of 2027. This integrated mine‑to‑port logistics chain ensures efficient, low‑cost transport of aggregates to key markets. For equipment buyers, the Fenghuangling project demonstrates that large‑scale aggregate operations require reliable, high‑capacity equipment that can sustain continuous production and integrate with complex logistics systems. OCP Mechanical’s PE Series jaw crushers and HST Series cone crushers are engineered for heavy‑duty, continuous operation, with robust construction and low maintenance requirements that support long‑term production reliability. All product specifications, including capacity and power ratings, are continuously updated; for the latest parameters, please consult our online customer service.

Core processing equipment – crushing, screening, and sand making in one integrated line

The Fenghuangling Phase II production line integrates the three core processing stages—crushing, screening, and sand making—into a single, continuous flowsheet. The crushing circuit provides primary, secondary, and tertiary reduction to achieve the required feed size for downstream processing. The screening circuit separates material into multiple size fractions, enabling production of a range of aggregate products. The sand making circuit, using vertical shaft impact (VSI) crushers, produces high‑quality manufactured sand with consistent gradation and excellent particle shape. This integrated approach ensures that the plant can produce a full range of products—from fine manufactured sand to coarse aggregates—in a single production line, maximising operational efficiency and product flexibility. For quarry operators, this integrated model demonstrates that modern aggregate production requires a well‑engineered combination of equipment types, each selected for its specific role in the process. OCP Mechanical offers complete processing solutions that can be configured to match this integrated 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.

Screening and classification – delivering specification‑grade products

Screening is a critical stage in any aggregate processing plant, determining the final product size fractions and ensuring that each product meets the required specifications. The Fenghuangling plant uses multiple screening stages to separate crushed material into different size fractions, enabling production of a range of aggregate products for different applications. High‑efficiency screening equipment ensures consistent product quality, low moisture content, and minimal fines carryover. For operators producing aggregates for high‑specification concrete and asphalt applications, screening accuracy is essential for meeting customer requirements and maintaining product quality. OCP Mechanical’s S Series vibrating screens are engineered for high‑capacity, accurate classification, with robust construction, adjustable vibration parameters, and easy‑access screen media that enable consistent performance in the most demanding applications.

The role of VSI sand making in premium manufactured sand production

The sand making circuit is a key differentiator for modern aggregate plants. VSI crushers produce manufactured sand with consistent gradation, excellent particle shape, and low flakiness—properties that are essential for high‑performance concrete and asphalt applications. The Fenghuangling plant’s VSI sand making circuit enables production of premium manufactured sand that meets the strict specifications required for major infrastructure projects. For operators, investing in high‑performance VSI sand making equipment is essential for capturing the growing demand for manufactured sand, particularly as natural sand resources become scarcer and regulations tighten. OCP Mechanical’s VSI 6X series sand making machines are engineered with advanced rotor designs and intelligent control features that deliver consistent, high‑quality manufactured sand with low operating costs. By choosing equipment designed for premium sand production, operators can differentiate their products and command premium prices in competitive markets.
