The rapid expansion of large open-pit mines and high-capacity aggregate production bases has raised higher requirements for primary crushing equipment. Most mining projects are plagued by excessive energy consumption, frequent replacement of wearing parts, high infrastructure investment and unstable continuous operation. To solve these industry pain points, DAHONGLI has upgraded the PEV series jaw crusher with all-round structural optimization. This high-performance crushing equipment is specially designed for large-scale mining primary and secondary crushing scenarios, delivering tailored turnkey solutions to help mining enterprises achieve stable production, energy conservation, low maintenance and overall operational cost reduction.
1. Versatile Application Scenarios of DAHONGLI PEV Jaw Crusher for Large Mines
Engineered for ores with a maximum compressive strength of 300MPa, the DAHONGLI PEV jaw crusher features strong adaptability to both soft and hard materials, covering diverse large-scale mining and resource recycling scenarios. It serves as the core primary crushing equipment for various large mine production lines:
• Large Metal Mining Projects: Efficient primary crushing for bulk raw ores including gold, iron, manganese and copper ores, perfectly matching 24-hour uninterrupted operation of multi-million-ton open-pit mine production lines.
• Large Non-metal Stone Mines: Reliable processing of high-hardness rocks such as granite, basalt, limestone and quartzite for aggregate production and stone processing projects.
• Metallurgy & Solid Waste Recycling: Ideal for pre-processing metallurgical raw materials, as well as resource regeneration and crushing of mine tailings and construction solid waste.
Equipped with an optimized deep V crushing chamber and super-large feeding port, the seven standardized models of the PEV series support a maximum feeding size of 1200mm. Large raw stones mined from open-pit mines can be directly fed into the equipment without secondary crushing and screening, greatly simplifying front-end mining processes, reducing auxiliary equipment investment and improving the overall operational efficiency of large mines.
2. Six-dimensional Technical Upgrades to Help Large Mines Reduce Costs and Increase Efficiency
Aiming at the high-load and long-cycle operation characteristics of large mining sites, DAHONGLI has carried out comprehensive technical iterations on the PEV jaw crusher, realizing breakthroughs in energy saving, wear resistance, equipment stability, infrastructure cost control and intelligent operation, and creating high-value crushing solutions for large mines.
2.1 Optimized Transmission Structure, Effectively Reducing Operational Energy Consumption
The PEV jaw crusher adopts an upgraded four-bar transmission structure, with a customized crushing stroke for high-load mining working conditions, which eliminates invalid material extrusion resistance and energy loss. Combined with the precisely balanced movable jaw component design, the unit energy consumption of crushing operation is reduced by up to 15% under the same processing capacity. For large mines with long-term continuous operation, the equipment can save substantial electricity costs throughout the service cycle.
2.2 High-strength Wear-resistant Materials, Extending Service Life of Consumable Parts
By optimizing the operating trajectory of the discharge opening, the equipment effectively reduces abnormal friction between ores and tooth plates. The movable jaw plates, fixed jaw plates and side guard plates are all made of high-quality hot-rolled wear-resistant alloy steel. The service life of core vulnerable parts is increased by 20%, which significantly reduces the frequency of equipment shutdown for parts replacement, cuts down consumable procurement costs and lowers daily maintenance workload for large mines.
2.3 Reinforced Combined Structure, Improving Overall Equipment Stability
Different from the traditional welded frame structure with poor fatigue resistance, the DAHONGLI PEV jaw crusher adopts an innovative combined box-type frame. This structural upgrade improves the equipment’s shock resistance and deformation resistance during high-hard rock crushing. The overall service life of the equipment is 40% longer than that of ordinary jaw crushers, with lower failure rate, effectively ensuring stable and high-yield operation of large-scale mining production lines.
2.4 Exclusive Inclined Design, Cutting Mine Infrastructure Investment
The unique inclined body layout greatly lowers the overall installation height of the equipment. For new large mine construction and old mine renovation and expansion projects, it can effectively reduce the construction cost of factory steel structures, civil engineering and equipment hoisting. The rapid deployment of crushing equipment shortens the project construction cycle and controls the overall investment cost of mining projects from the source.
2.5 Dual Intelligent Adjustment Modes, Adapting to Smart Mine Construction
To meet the differentiated needs of traditional and intelligent mines, the PEV series jaw crusher is equipped with two flexible discharge particle size adjustment modes:
• Mechanical Wedge Adjustment: Simple, stable and maintenance-free, suitable for conventional large and medium-sized mining production lines.
• Hydraulic Automatic Adjustment: Supports one-click particle size adjustment without shutdown, which is compatible with unmanned and intelligent modern large mines.
In addition, optional configurations such as automatic lubrication systems and flywheel safety shields can further reduce manual operation risks and realize intelligent and low-labor operation of mining equipment.
3. Full-series Model Coverage, Accurately Matching All Levels of Mine Production Capacity
DAHONGLI PEV jaw crusher has launched seven standardized models, forming a complete capacity coverage system from small quarries to super-large open-pit mines with an annual output of tens of millions of tons, fully adapting to the diversified configuration needs of large mine crushing solutions:
• Feeding particle size range: 400mm - 1200mm, supporting direct feeding of large raw materials
• Matching motor power: 55kW - 400kW, with complete power gradient coverage
• Hourly processing capacity: 65t/h - 1910t/h, meeting high-yield operation of large mines
The equipment is equipped with a professional particle size control curve, with uniform and stable discharge particle size. It can be perfectly connected with secondary crushing and screening equipment, ensuring the efficient and orderly operation of the entire large mine crushing and processing production line.
4. DAHONGLI Full-process One-stop Solution for Large Mining Projects
