In the spring of 2026, exciting news emerged from the infrastructure construction front on western Sichuan Plateau: the second 1500T/H crushing production line, customized by Chengdu Dahongli Machinery Co., Ltd. (hereinafter referred to as Dahongli) for the key project in Ruoergai, has completed full shipment and successfully arrived at the site, with installation and commissioning fully underway. This re-cooperation between Dahongli and the customer is built on mutual trust, and also reflects Dahongli’s profound technical accumulation and high market recognition in the high-end manufacturing of crushing production lines.
Tailored for Plateau Conditions, Effectively Overcoming Challenges
Unlike ordinary working environments, infrastructure construction on Ruoergai Plateau is confronted with three major obstacles: low air pressure, large temperature variations, and complex terrain. Instead of adopting standardized equipment, Dahongli developed a customized technical plan for this 1500T/H crushing production line based on its extensive industry experience and expertise.
The core equipment of the project—the PEV1500×2000 jaw crusher—serves as the foundation of the entire solution. Adopting a modular non-welded structure, it boasts high installation precision and structural stability. The optimized cavity design and large-size bearing configuration enable it to maintain excellent impact resistance and processing efficiency even in high-altitude and low-oxygen environments, efficiently handling various hard rocks with compressive strength up to 300Mpa and providing sufficient, high-quality raw materials for subsequent crushing processes.
Integrated Chain Collaboration, Producing Premium Aggregates
To guarantee the quality of the final products, the entire crushing production line has established a closed-loop full-process processing system, consisting of PEV1500×2000 jaw crusher, PYY single-cylinder hydraulic cone crusher, 8HL high-efficiency impact crusher, and ZSW vibrating feeder.
With a processing capacity of 1500T/H, this efficient configuration realizes integrated intelligent operation from raw material feeding to finished product discharge. The sand and gravel aggregates produced feature a perfect cubic shape, extremely low needle and flake content, and continuous, stable gradation. This not only meets the strict requirements for high strength and durability ofsand and gravel aggregates in local key projects such as roads and municipal engineering in Ruoergai, but also provides essential building material support for improving regional infrastructure quality.
Full-Process Support, Building Trust Through Service
The customer’s repurchase is the most direct recognition of Dahongli’s service system. From preliminary on-site investigation and plan customization, to strict quality control during production and manufacturing, and on-site installation, commissioning, and training in Ruoergai, Dahongli’s professional service team provides full follow-up support and 24/7 technical assistance and operation guidance.
This full-lifecycle one-stop service model effectively addresses the operation and maintenance challenges faced by customers in remote plateau areas, ensuring the crushing production line operates efficiently, continuously, and stably after commissioning.
Looking Ahead, Empowering Development with Intelligent Manufacturing
The successful delivery of this 1500T/H crushing production line in Ruoergai has further strengthened Dahongli’s leading position in the crushing production line and plateau mining machinery segments. In the future, Dahongli will continue to deepen technological innovation, continuously optimize equipment solutions for special plateau environments like Ruoergai, and use more intelligent, efficient, and reliable sand and gravel aggregates processing equipment to continuously empower infrastructure development in western Sichuan Plateau and across the country, injecting sustained Dahongli momentum into high-quality development.
