Dahongli: Premium Large-Scale Mining Crushing Solutions for Global Metal & Non-Metal Mines

Chengdu Dahongli Machinery Co., Ltd. (Stock Code: 300865) has accumulated rich industrial expertise in mineral processing machinery. Evolving from a single equipment producer to an integrated international contractor, the firm focuses on turnkey crushing plants tailored for large-scale mineral deposits. By virtue of mature technical reserves, diversified machinery portfolios and cross-border service capabilities, Dahongli consistently delivers high-performance solutions to global mining investors, advancing sustainable, intelligent and low-carbon development within the mineral industry.

Proven Engineering Competence in Extreme & High-Altitude Mining Environments

As global mineral exploitation gradually extends to remote and harsh terrains, customized processing technology has become essential for complicated mine construction. Dahongli successfully completed the construction and commissioning of a 1 million-ton lead-zinc mineral processing project located at an altitude of 4,900 meters in Xizang. This operational facility offers valuable practical references for high-altitude metallic mineral exploitation worldwide.

Featuring frigid temperatures, oxygen scarcity and tough ore hardness, the plateau site imposes rigorous criteria for mechanical durability, wear resistance and environmental adaptability. Leveraging massive data accumulated from global mine projects, Dahongli engineered a bespoke crushing and screening system adapted to plateau environments. The technical configuration incorporates vibrating feeding units, primary jaw crushers, hydraulic cone crushers, impact crushing machines and multi-layer vibrating screens. The coordinated mechanical workflow satisfies systematic processing demands including ore fragmentation, gangue removal and particle classification for lead-zinc minerals.

The fully operational production line generates various graded mineral products, including fine ore, mineral concentrate and manufactured aggregate. Precise material classification optimizes raw mineral utilization and enhances economic profitability for mining enterprises. The seamless commissioning validates Dahongli’s reliable mechanical performance and exceptional technical adaptability in high-hardness metallic mineral processing and extreme geographical environments.

One-Stop Industrial Solutions Covering Diverse Global Mining Types

As a publicly traded enterprise in the mining equipment sector, Dahongli prioritizes actual demands of global mine operators. It establishes a complete industrial service chain including geological exploration, operational condition evaluation, process customization, mechanical R&D, intelligent manufacturing, on-site installation and long-term operational maintenance. The company provides scalable crushing lines with hourly throughput ranging from 50 tons to 3,000 tons, applicable for ferrous and non-ferrous minerals such as lead-zinc, iron, gold and copper, as well as common non-metallic rocks including limestone, granite and basalt.

1. Industrial Manufacturing Strength for Bulk Heavy-Duty Machinery Supply

Dahongli manages three standardized production and research campuses covering 270,000 square meters. Equipped with precision machining tools and automated production workshops, the group realizes mass manufacturing of heavy-duty mining machinery, including gyratory crushers, jaw crushers, cone crushers and high-pressure grinding rolls. Individual processing units are capable of super-high hourly throughput, meeting continuous and intensive production requirements of large-scale mines. The enterprise owns numerous proprietary technological achievements. Adopting non-welded modular frames and intelligent hydraulic systems, its machinery features outstanding impact resistance and simple maintenance, efficiently processing ores with compression strength below 300MPa and conforming to international environmental protection regulations.

2. Diversified Machinery Lineup for Multi-Stage Mineral Comminution

Dahongli develops hierarchical processing equipment matching the whole crushing workflow of metallic minerals, covering primary crushing, medium crushing, fine crushing and ultra-fine comminution:

• Primary Crushing: Reinforced jaw crushers lower energy consumption by 15%, optimized for coarse fragmentation of high-hardness metallic ores.
• Medium & Fine Processing: Intelligent single-cylinder hydraulic cone crushers reduce power consumption by 30%, perfectly suited for iron and lead-zinc mineral processing.
• Ultra-Fine Comminution: High-pressure grinding rolls improve production efficiency by 20%-30% while cutting electric consumption, effectively lowering operational costs for mineral concentrators.
• Feeding & Screening Machinery: Inertial vibrating feeders and multi-frequency vibrating screening machines ensure accurate particle classification and steady material transportation.

Dahongli’s integrated processing systems have been widely deployed across global mining zones, covering plateau metallic mines in China, mineral exploitation bases in Africa, and aggregate production projects in Southeast Asia. Dependable mechanical performance and personalized processing schemes earn consistent recognition from international clients.

International Market Layout & Global After-Sales Service System

Sticking to the dual development strategy of domestic consolidation and international expansion, Dahongli keeps accelerating global market distribution. Its qualified mining machinery is exported to Southeast Asia, Central Asia, Africa and other emerging mineral regions. The localized overseas service framework offers round-the-clock remote monitoring and on-site technical guidance, ensuring stable and continuous operation of international mining projects.

Committed to empowering the global mineral industry with advanced mining technology, Dahongli consistently upgrades mechanical structures and processing craftsmanship. The enterprise remains dedicated to delivering intelligent, energy-saving and eco-friendly turnkey solutions for global mineral resources development.

In the long run, Dahongli will keep focusing on global mineral resource exploitation demands. Supported by advanced technologies, durable machinery and comprehensive industrial services, the company will assist more large-scale mining projects in stable construction and sustainable operation, promoting high-quality advancement of the global mining industry and consolidating its competitive advantages in the international heavy-duty mine crushing sector.
