With decades of experience in the mining machinery industry, Chengdu Dahongli Machinery Co., Ltd. (Stock Code: 300865) has evolved from a single equipment manufacturer into a comprehensive solution provider for large-scale crushing production lines for metal and non-metal mines. Supported by accumulated professional technologies, complete equipment portfolios and global service capabilities, Dahongli continuously empowers mining projects at home and overseas, promoting the efficient, environmentally friendly and intelligent development of the mining industry.
High-Altitude Mine Project Demonstrates Technical Strength Under Harsh Working Conditions
As mining operations expand into high-altitude and complex terrains, Dahongli delivers customized technical solutions to address industrial challenges. The recently commissioned lead-zinc mine project in Xizang, with an annual output of 1 million tons and an altitude of 4,900 meters, serves as a practical demonstration for high-altitude metal mine development worldwide.
The project features rigorous operating conditions including low temperatures, oxygen deficiency and high-hardness ore, which set high requirements for equipment reliability, wear resistance and environmental adaptability. Drawing on abundant practical experience from numerous mining production lines, Dahongli customized a dedicated crushing and screening system for plateau conditions. The core equipment includes ZSW vibrating feeders, PEV jaw crushers, PYY single-cylinder hydraulic cone crushers, PF impact crushers and YK vibrating screens. The coordinated operation of all equipment meets the processing requirements for crushing, waste separation and classification of lead-zinc ore.
Currently, the production line operates stably and produces diversified products, including 0-12mm fine ore, 10-45mm concentrate, 0-5mm manufactured sand and various aggregates. The refined classification improves resource utilization efficiency and enhances the market competitiveness of finished mineral products. The one-time successful commissioning verifies Dahongli’s technical capacity and equipment reliability in processing high-hardness metal ore and adapting to extreme working conditions.
Full-Cycle Services Cover Global Metal and Non-Metal Mining Scenarios
As a listed enterprise in the mining machinery sector, Dahongli focuses on global mining demands and establishes a full-life-cycle service system covering geological survey, working condition analysis, solution customization, equipment research and development, manufacturing, installation, commissioning and after-sales maintenance. The company provides complete crushing production lines with hourly capacity ranging from 50 tons to 3,000 tons for metal mines such as lead-zinc, iron, gold and copper mines, as well as non-metal mines including limestone, granite and basalt.
1. Advanced Manufacturing Capacity Supports Large-Scale Equipment Delivery
Dahongli owns three modern R&D and manufacturing bases covering a total area of 270,000 square meters. Equipped with high-end processing facilities and intelligent production lines, the enterprise is capable of mass-producing large-scale mining equipment including jaw crushers, cone crushers, gyratory crushers and high-pressure grinding rolls. The hourly output of single equipment can reach over 1,000 tons, satisfying the continuous and intensive production demands of large mines. The company holds multiple technical patents. Adopting modular non-welded structures and intelligent hydraulic control systems, the core equipment features strong impact resistance, low energy consumption and convenient maintenance, capable of processing ores with hardness up to 300MPa while complying with international environmental standards.
2. Complete Equipment Portfolio Adapts to Diverse Ore Types
Dahongli has developed a full-range equipment portfolio covering coarse crushing, medium crushing, fine crushing and ultra-fine crushing procedures for metal mines:
• Coarse Crushing: PEV jaw crusher with optimized structure reduces energy consumption by 15%, suitable for coarse crushing of high-hardness metal ore.
• Medium & Fine Crushing: PYY single-cylinder hydraulic cone crusher equipped with an intelligent adjustment system cuts energy consumption by 30%, ideal for processing iron ore and lead-zinc ore.
• Ultra-Fine Crushing: G-series high-pressure grinding roll increases productivity by 20%-30% and reduces power consumption by 15%-35%, improving mineral processing efficiency and lowering operational costs.
• Screening & Feeding Equipment: YK vibrating screens and ZZG inertial vibrating feeders ensure accurate classification and efficient screening.
Dahongli’s complete sets of equipment have been applied in numerous mining projects, including domestic high-altitude metal mines, iron mines and gold mines, as well as infrastructure aggregate projects in Southeast Asia and mineral exploitation sites in Africa. Stable equipment performance and customized solutions have gained wide recognition from global clients.
Global Strategic Layout Builds a Renowned Brand of Chinese Mining Machinery
Adhering to the development strategy of domestic consolidation and global expansion, Dahongli accelerates international layout. Its products are exported to Southeast Asia, Africa, Central Asia and other regions. A sound overseas service network provides 24/7 remote operation and on-site technical support to ensure stable operation of global mining projects.
Committed to the mission of manufacturing reliable mining machinery and promoting industrial progress, Dahongli takes technological innovation as the core driving force to upgrade equipment performance and processing techniques. The company dedicates itself to providing intelligent, efficient and eco-friendly comprehensive solutions for global metal and non-metal mines.
In the future, Dahongli will continue to focus on global mining demands.
