The party flag flutters at the frontline, and party building empowers development. Recently, led by the branch committee of the Communist Party of China Chongqing Sanming Heavy Industry Co., Ltd., key personnel from the marketing center, technology research and development center, and customer service center organized a special activity called "Party Building Leads the Way in Mining". They visited the material processing sites and sand and gravel aggregate production bases of the high-speed rail projects in western China. With "high-standard quality, high-efficiency intelligence, and green safety" as the core guidance, they conducted on-site inspections to assess the effectiveness of high-standard material solutions. They used the red of party building to lead the blue of industry, contributing Sanming's strength to national infrastructure and the strategy of building a powerful transportation nation.

This event focused on key projects of the Yibin-Fuling High-Speed Railway and the Chongqing-Wanzhou High-Speed Railway in Chongqing, visiting project cooperation sites such as China Railway No.5 Engineering Group Co., Ltd., China Railway 11th Bureau Group Co., Ltd., and China Railway Major Bridge Engineering Group Co., Ltd., to conduct a comprehensive on-site inspection of the operating status of the crushing and screening equipment provided by Sanming Heavy Industry and the quality of finished aggregates. Data feedback showed that the customized process plan designed by the enterprise met all high-standard project requirements precisely, earning recognition from the partners with its core strength.

With over 30 years of deep industry experience, we have always taken technological innovation as our foundation and major engineering needs as our guide," said Wan Feng, General Manager of Chongqing Sanming Heavy Industry. From the Chongqing-Guizhou High-Speed Railway, Chongqing-Xichang High-Speed Railway to the Chongqing-Xiamen High-Speed Railway and Xichang-Kunming High-Speed Railway, from the Guiyang-Guangzhou High-Speed Railway, Chengdu-Dazhou-Wanzhou High-Speed Railway to the Chengdu-Chongqing Middle Line High-Speed Railway, the company has provided complete line equipment for numerous national-level high-speed railway projects. Through practice, we have accumulated core technologies, developed and launched multiple intelligent, efficient, and innovative crushing host products, and established an industry-leading full-process technology solution system.

Adopting a one-cut boring process and a high-quality steel plate welded frame, the deep cavity crushing eliminates dead zones; the electromechanical integration optimization design achieves fast feeding, no material blockage, a large crushing ratio, high efficiency, steady capacity improvement, and durability, firmly establishing the "first line of defense" in the crushing process.

The original three-chamber five-stage crushing and shaping process is suitable for secondary intermediate crushing. It can adjust the proportion of crushed stone and finished sand materials according to production needs. The finished crushed stone has a low needle-like content and excellent roundness, laying the foundation for high-quality aggregates.

The optimized design of the four-blade impeller, iterative upgrades of the crushing chamber shape, and innovative shaft combination methods have significantly improved the shaping and sand making effects. Additionally, the operation is simple, and the functions of shaping and sand making can be quickly interchanged, creating a high-quality aggregate with "attractive appearance".

Scientific optimization of the five-stage crushing chamber enables precise control over the crushing and striking angles of materials. Multiple breakthroughs have been achieved in terms of sand production yield, motor energy consumption, powder content control, and particle shape grading. High-quality sand production can be achieved for materials ranging from 3-5mm, 5-10mm, to those below 60mm, with rounded particle shapes and continuous grading, demonstrating industry-leading advantages.

Guided by party building, Sanming Heavy Industry has deeply integrated processes such as crushing, screening, washing, powder selection, dust removal, sewage treatment, and intelligent control. It precisely regulates the powder content, moisture content, and cleanliness of finished products. Coupled with scientific stacking management, it comprehensively ensures excellent gradation, superior particle shape, and stable quality of finished aggregates. This approach maximizes both resource utilization and economic benefits, providing full-chain support for the construction of green and smart mines in infrastructure projects.
