Traversing the Wuling Mountains, one can hear the roar of the Yangtze River. Located in Hefeng County, Enshi, Hubei Province, this site is the construction site of Section 8 of the newly-built Yichang-Fuling High-Speed Railway.
To achieve efficient synergy between resource recycling and engineering construction, the gravel yard project for Hefeng Station in the Hubei section of the newly-built Yichang-Fuling High-Speed Railway is being constructed as scheduled. The complete set of equipment for this gravel yard is provided by Chongqing Sanming Heavy Industry, designed to meet high standards of economic efficiency, environmental protection, energy conservation, high efficiency, intelligence, and safety. The coarse crushing process adopts a semi-submerged design, utilizing natural terrain to reduce footprint and rationally arrange the production line.
The PEW jaw crusher is used for coarse crushing, featuring a deep-cavity electromechanical integrated structure that ensures no dead zones in crushing, high productivity, low power consumption, and durability.
The VF-type impact crusher is selected for secondary crushing due to its high proportion of crushed stone, high output, and good particle shape, which lays the foundation for the quality of the finished crushed stone aggregates.
Equipped with a UZL vertical shaft impact crusher for shaping, it significantly reduces the needle-like content of crushed stone.
Equipped with a VCX ultra-fine sand making machine for fine crushing, it achieves energy saving and consumption reduction, precise powder control, and produces high-quality finished sand with round particles and excellent grading, meeting the high standards for materials used in high-speed railways.
The DYS double-shaft vibrating screen is used for graded screening, and the water washing process, stone powder silo, and finished aggregate storage silo are designed.
Sand and gravel are the foundation of high-speed railway projects. Chongqing Sanming Heavy Industry, with its leading equipment and processing technology, empowers the construction of high-speed railway projects in the western region, making the distant places no longer seem far away. Every inch of progress in the high-speed railway construction embodies the perseverance of the builders and also propels the promising future of the Yangtze River Delta, the middle reaches of the Yangtze River, and the Chengdu-Chongqing urban agglomeration!

Preface: The Wanliang Ancient Post Road, as an important land route hub connecting Wanzhou and Liangping in ancient times, is the essential passage for Jingchu, Wu, and Yue regions to enter Sichuan and reach western Sichuan. It is also a key component of the "Litchi Road", carrying the thousand-year historical memory of "a horse riding through the dust, making the concubine laugh", connecting the past prosperity of Chang'an and the Shu region, and witnessing the cultural integration between the southwest and the Central Plains.

Recently, the administrative functional departments of Chongqing Sanming Heavy Industry organized a 10-kilometer public welfare hiking team-building activity along the Wanliang Ancient Post Road, with the theme of "Traversing Ancient Paths to Recall Civilization, Practicing Public Welfare to Protect Nature". Sanming people temporarily left their desks and stepped into the green mountains and clear waters, measuring the historical depth of the thousand-year-old ancient road with their feet and conveying their responsibility and commitment to green environmental protection through their actions.
"The Sichuan Road is steep and treacherous, reaching high into the sky, and at the Qin Pass, we halt our horses to gaze upon the western plains." For administrative staff who spend years working at a desk, this hiking trip is not only a dual training of physical fitness and willpower, but also an immersive public welfare practice. On the way, the team members held tools in hand, meticulously cleaning up waste along the ancient road, strictly adhering to the environmental protection concept of "leaving no trace except footprints," integrating the original intention of public welfare into every step forward, and letting civilized actions preserve the style and features of the ancient road.

The sunset glow accompanied our return journey, leaving us physically exhausted yet spiritually enriched. This activity not only helped everyone gain a strong physique and team synergy, but also allowed us to appreciate the historical heritage by touching the ancient road relics and cultivate a deep sense of awe while being close to nature. The tenacious strength and ecological sentiment derived from the ancient road will be transformed into a driving force for progress in our work, empowering Sanming people to delve deeper into their positions and fulfill their mission with a more vigorous attitude.

In the future, Chongqing Sanming Heavy Industry will continue to deeply engage in public welfare practices, create more team-building activities that embody both cultural connotations and social responsibility, align enterprise development with nature conservation, and resonate industrial value with cultural heritage. Together with all employees, we will create value while deeply cultivating social responsibility, embarking on a new journey of harmonious coexistence with nature, history, and society.

Introduction: In December 2024, East Hope Group's Chongqing Fengdu Phase I sand making building issued a bidding announcement for technical renovation. Chongqing Sanming Heavy Industry emerged with its superior performance advantage of the VCX ultra-fine sand making machine, replacing one vertical shaft impact crusher and one roller mill with one VCX ultra-fine sand making machine. In July 2025, the company's Phase III sand making building underwent another technical renovation, and Sanming Heavy Industry's VCX ultra-fine sand making machine successfully replaced two of the six sand making machines in the building, achieving a repeat purchase of VCX ultra-fine sand making machines.

Repurchasing is the greatest trust and recognition that customers have for a product. Recently, in the technical renovation project of the sand making building in the third phase of Chongqing Fengdu, East Hope Group once again purchased two VCX ultra-fine sand making machines from Chongqing Sanming Heavy Industry to replace two of the six sand making main machines. Currently, four of the six sand making main machines in the sand making building have adopted the VCX ultra-fine sand making machines from Chongqing Sanming Heavy Industry, achieving three repurchases of products.

Three times of repurchasing VCX ultra-fine sand making machine have been installed in place

Three repurchases witness excellent quality: the performance advantage of VCX ultra-fine sand making

• High productivity and low energy consumption: Single motor operation, integrated motor design, compared to traditional sand making main machines, energy-saving motors consume 50% less energy, saving millions of electricity bills per year for a single device. Moreover, the sand making efficiency is greatly improved, and the output is increased by 20t/h on the original basis
•Efficient powder reduction: Adopting a five-stage crushing chamber design with adjustable crushing chamber gaps, it achieves a precise powder reduction of 10 percentage points compared to traditional sand making main machines, successfully reducing stone powder by 5% on the original basis.
•High finished product quality: The finished sand produced by the VCX ultra-fine sand making machine has good particle shape, with a circularity greater than 0.82, and excellent continuous grading, meeting the material standard for medium sand in Zone 2.

Customer satisfaction: the greatest compliment to a product

According to the production manager of the project, "After several technical modifications and verifications, Sanming Heavy Industry's VCX ultra-fine sand making machine has exceeded expectations in terms of stability, sand output quality, and energy consumption. This is the reason why we chose to repurchase it again."

With a long-term perspective, we strive for innovative development. Chongqing Sanming Heavy Industry has always been committed to achieving mutual value with our customers. We firmly believe that only product technologies that can withstand market scrutiny can earn long-term trust and support from users. Every repeat purchase marks the beginning of a new partnership. Sanming Heavy Industry looks forward to collaborating with more industry partners, leveraging our technical expertise and service guarantees to deliver satisfaction, and jointly creating a bright future for the sand and gravel industry!
