2 Million TPY Aggregate Plant Successfully Commissioned – OCP Mechanical Offers Complete Crushing & Screening Solutions for High‑Quality Sand and Stone Production

Why a fully integrated crushing and screening solution is the key to efficient, high‑quality aggregate production

The aggregates industry is increasingly moving toward large‑scale, fully integrated processing plants that can deliver consistent product quality, high throughput, and reliable operation. A recent example is the successful commissioning of the Hubei Baoye Caijiawan Mine project in Yichang, Hubei Province – a 2‑million‑tonne‑per‑year (TPY) construction limestone operation that has now obtained its safety production permit and entered full legal operation. The project represents a total investment of approximately RMB 650 million and serves as a key resource security project for the Yichang municipal government. It produces premium washed aggregates and high‑calcium stone products across a full range of sizes, from 0‑5 mm manufactured sand to 20‑31.5 mm crushed stone and 50‑80 mm high‑calcium stone, serving concrete and road construction markets across the Yangtze River Economic Belt. At OCP Mechanical Company, with over 40 years of manufacturing experience, we supply complete crushing and screening plants – including PE Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines – designed to deliver the same level of performance, reliability, and product quality for aggregate operations worldwide, all at factory‑direct prices.

Complete equipment package for a 2‑million‑TPY operation

The Caijiawan project utilises a full suite of crushing and screening equipment, featuring a jaw crusher + cone crusher + vertical shaft impact (VSI) wet processing circuit. The primary equipment package includes 2 jaw crushers, 3 cone crushers, and 4 VSI crushers, along with multiple large‑capacity vibrating screens arranged across three decks. This comprehensive equipment lineup enables the plant to process limestone efficiently and consistently while producing multiple product sizes in a single integrated flow. The wet processing circuit, incorporating VSI crushers and washing equipment, ensures that the final manufactured sand and aggregates meet the stringent specifications required for modern concrete and asphalt applications. The plant's ability to produce both dry and wet products across a wide size range demonstrates the versatility and capability of a well‑designed, fully integrated aggregate processing system. At OCP Mechanical, our complete plant solutions are engineered to deliver the same combination of high capacity, product flexibility, and consistent quality, enabling operators to meet the most demanding market requirements. All product specifications, including capacity and power ratings, are continuously updated; for the latest parameters, please consult our online customer service.

Wet processing for premium manufactured sand and aggregates

A key feature of the Caijiawan project is its wet processing capability, which enables the production of premium washed aggregates and high‑quality manufactured sand. Wet processing removes fine particles, clay, and other contaminants that can affect product quality, producing a clean, specification‑grade material suitable for high‑performance concrete and construction applications. The integration of VSI crushers with washing and dewatering equipment ensures that the final sand product has consistent gradation, excellent particle shape, and low moisture content – all essential properties for high‑quality construction materials. For operators considering investment in new aggregate production capacity, wet processing capability is increasingly important as market specifications tighten and demand for premium products grows. OCP Mechanical's complete plant solutions can be configured with wet processing circuits, including P Series sand screw washers, dewatering screens, and hydrocyclone systems, enabling operators to produce high‑quality manufactured sand and washed aggregates that command premium prices. Prices are for reference only and are subject to change based on configuration and market conditions.

From raw feed to multiple finished products – a complete integrated solution

The Caijiawan plant processes run‑of‑quarry limestone into a range of finished products through a carefully designed sequence of crushing, screening, and washing stages. The jaw crushers provide primary reduction, the cone crushers handle secondary and tertiary crushing, and the VSI crushers produce the final shaped sand and fine aggregates. Multiple screening stages separate the material into different size fractions, enabling the production of multiple product sizes from a single production line. The wet processing circuit ensures that the manufactured sand and fine aggregates meet the highest quality standards. This integrated approach – from primary crushing to final product classification – is essential for achieving the efficiency and product quality that modern aggregate operations require. At OCP Mechanical, we design and supply complete integrated solutions that cover every stage of the process, from feeders and primary crushers to screens, washers, and conveyors. Our single‑source capability simplifies procurement, ensures compatibility between equipment, and provides a single point of responsibility for after‑sales support.

The importance of reliable equipment for large‑scale aggregate production

Large‑scale aggregate operations like the Caijiawan project demand equipment that can operate continuously, deliver consistent product quality, and minimize downtime. The equipment package – jaw crushers, cone crushers, VSI crushers, and screens – must be robust, reliable, and designed for easy maintenance. In operations of this scale, even a brief unplanned shutdown can result in significant lost production and revenue. Operators need equipment that is built to withstand the demands of continuous operation, with features such as heavy‑duty construction, advanced hydraulic systems, and user‑friendly controls that simplify operation and maintenance. At OCP Mechanical, our equipment is engineered with these requirements in mind. Our PE Series jaw crushers, HST Series cone crushers, and VSI 6X sand making machines are built with high‑quality components and are designed for reliable performance in the most demanding applications. We provide comprehensive after‑sales support, including spare parts availability, technical assistance, and on‑site training, to help our customers maintain continuous, productive operation.
