Struggling with Hard Rock & Mud in Congo
Recently, we received on-site photos from a customer in the Democratic Republic of Congo (as shown above). The images show a towering 15-meter-high reddish-brown rock face with hard, well-developed joints, and large chunks of black basalt rubble piled at the base, alongside a muddy ditch a typical scene in mining areas of the Democratic Republic of Congo and indeed the entire Central African region: high-hardness rock layers, complex geological structures, a humid and rainy environment, and limited operating space.
The customer's core requirement was clear: to find a mobile crushing plant capable of chewing through these hard rocks and operating flexibly and efficiently under such challenging conditions. As a mining crushing equipment manufacturer with twenty years of experience, we understand that generic solutions won't work here; customized, highly adaptable solutions are the key to success.
I. In-depth Analysis of the Core Challenges in the Democratic Republic of Congo Mining Area
From the customer's photos, we can identify four major challenges that the equipment must address:
1. High Rock Hardness and Abrasiveness: The reddish-brown rock face and black basalt blocks typically belong to medium-to-high hardness rocks (Mohs hardness 5-7). This places extremely high demands on the impact resistance of the crushing equipment's main unit and the wear resistance of the hammer/jaw plates.
2. Complex Terrain and Harsh Road Conditions: The muddy ditches and earth platforms in the pictures indicate that the mining area roads are muddy and the ground bearing capacity is uneven. The equipment needs strong off-road capabilities and chassis stability to ensure smooth relocation even during the rainy season.
3. Limited Space and Mobile Operation Requirements: Judging from the temporary shelters and layout, the mining face may shift over time. The integrated, one-stop operation mode of tracked or wheeled mobile crushing plants can keep pace with the mining face, saving significant infrastructure construction and material transfer costs.
4. Rainy and Humid Climate: The equipment's electrical and hydraulic systems require moisture-proof and dust-proof sealing designs to ensure reliable operation and longevity in a hot and humid environment.

II. Solution Overview: Our DRC Special Mobile Crushing Plant
Addressing these pain points, our solution is not simply providing a single piece of equipment, but a complete, customizable crushing system. Our core equipment utilizes a combination of track-mounted jaw crusher and impact crusher (or cone crusher). The track-mounted jaw crushing station acts as the primary crusher, easily handling the large, hard rocks shown in the image thanks to its powerful crushing force and robust structure; the subsequent mobile impact crusher (for medium-hard rocks) or cone crusher (for extremely hard, abrasive rocks) handles secondary and tertiary crushing, producing ideal finished product particle shapes. The entire unit uses a heavy-duty track chassis with low ground pressure, easily traversing the rugged terrain shown in the image; the intelligent hydraulic control system allows for one-button start/stop and rapid deployment/folding, perfectly adapting to the frequent relocation required in this type of operation.
III. Our Core Advantages: Why Choose Us?
• Twenty Years of Expertise in Complex Working Conditions: We have accumulated thousands of successful cases both domestically and internationally, and are intimately familiar with the geological conditions and operational practices in places like the Democratic Republic of Congo and Zambia. Our equipment incorporates fatigue resistance and corrosion resistance from the design stage.
• Truly One-Stop Customization: From analyzing your raw ore samples (similar to the rocks in the image) to recommending models, configuring dust and noise reduction modules, and providing auxiliary systems for mud and water treatment, to installation guidance and remote operation and maintenance, we provide full-process support.
• Leap in Efficiency and Productivity: Practical experience has shown that our customized mobile crushing production lines, by optimizing processes and reducing intermediate transfer steps, can help customers increase overall productivity by more than 30%, while significantly reducing fuel consumption and labor costs.
• Powerful Localized Service Network: We have service offices and parts warehouses in major mining areas in Africa, ensuring rapid response and minimizing your downtime.

IV. Successful Case Sharing: Victories in Similar Scenarios
Case Study: Copper-Cobalt Mine Project in Katanga Province, Democratic Republic of Congo
The client faced challenges almost identical to those shown in the image: high-hardness oxidized ore, seasonal rivers running through the mine, and dispersed work areas. We customized a combination of track-mounted jaw crusher + track-mounted cone crusher + mobile screening station for them. The equipment demonstrated exceptional adaptability: during the rainy season, it continued to operate thanks to its excellent mobility; when facing extremely hard ore veins, the cone crusher's layered crushing technology ensured consistent output particle size and production volume. After the project was put into operation, the annual processing capacity increased by 35%, and the equipment utilization rate reached 92%, far exceeding customer expectations.
V. Recommended Equipment Models (for the illustrated working conditions)
| Recommended Combination | Core Model | Applicable Scenarios and Advantages |
| Hard Rock Crusher Combination | Track-mounted Mobile Jaw Crusher (C series) + Track-mounted Mobile Multi-cylinder Hydraulic Cone Crusher (HPC series) | Designed specifically for extremely hard rocks such as basalt and granite shown in the diagram. The cone crusher uses layered crushing, resulting in excellent particle shape, long wear part life, and low overall operating costs. |
| Versatile and Flexible Combination | Track-mounted Mobile Impact Crusher (CI series) | Suitable for medium to high hardness rocks and scenarios requiring high particle shape quality. The integrated design allows for faster relocation and combines crushing and shaping functions. |
| Key Auxiliary Configurations | Heavy-duty Feeder, Mud-water Separation Module, Remote Intelligent Monitoring System | Addresses uneven feeding of muddy materials, electrical system protection, and remote diagnostic management needs, improving system robustness. |
VI. Frequently Asked Questions (FAQ)
Q1: Given the long rainy season in the Democratic Republic of Congo, how does the equipment ensure electrical safety?
A: Our equipment adopts protection standards above IP65, with special sealing and moisture-proof treatment for electrical control cabinets, motors, and wiring connectors. We also recommend building a simple rain shelter and having our service engineers conduct regular specialized inspections.
Q2: What are the replacement cycle and local supply of wear parts?
A: For highly abrasive rocks, we offer wear parts such as hammerheads/mantles made of ultra-high chromium alloy or composite ceramic inserts, which can extend the lifespan by 50%-100% compared to ordinary parts. We have central parts warehouses in South Africa and Kenya, ensuring that commonly used wear parts can be delivered to major mining areas in the Democratic Republic of Congo within two weeks.
Q3: What are the fuel consumption and operating costs of the equipment?
A: Our new generation models use electronically controlled high-pressure common rail engines and intelligent variable frequency technology, automatically adjusting power according to the load, saving 15%-25% energy compared to older equipment. We will provide a detailed Return on Investment (ROI) analysis report to give you a clear understanding of costs and benefits.
Q4: How long does it take from ordering to commissioning?
A: The delivery time for standard models is approximately 8-12 weeks. For highly customized configurations, we will determine the timeline after detailed discussions with you. We provide a turnkey service, including on-site installation and commissioning guidance, and operator training, to ensure you can start production quickly.
