Working Principle of Industrial-Grade Cutter Suction Dredger

Our cutter suction dredger adopts fully hydraulic continuous dredging technology, realizing underwater cutting, stirring, suction and long-distance pipeline transportation in one integrated process. It supports 24-hour uninterrupted operation with extremely high working efficiency.
1. High-Torque Hard Soil Cutting Equipped with heavy-duty hydraulic cutter head with thickened alloy cutter teeth, the dredger produces strong rotational torque underwater. It can actively peel and crush hard clay, hardened sediment, layered silt and small gravel that ordinary dredgers cannot handle, thoroughly solving the problem of unbreakable riverbed strata.
2. High-Concentration Slurry Mixing & Suction The matched dredge pump independently developed by Yuanyang adopts optimized flow channel design. The crushed sediment is fully stirred and mixed, forming uniform high-density slurry. The solid content can reach 40%–55%, far higher than ordinary dredgers, ensuring large output per hour.
3. Long-Distance Pressurized Delivery With strong pump pressurization capacity, the slurry can be transported 1000–3000 meters stably. By adding booster pump groups, the maximum conveying distance can reach more than 5000 meters, fully meeting large-area sand stacking and land reclamation filling requirements.
Cooperating with anchor positioning and swing winch system, the dredger performs layered comprehensive dredging with flat bottom and low residual, fully meeting engineering acceptance standards.

Core Advantages of Yuanyang Custom Cutter Suction Dredger

1. True Hard Soil Dredging Capacity

Many so-called cutter dredgers on the market only have decorative cutter heads with weak torque. Our upgraded hydraulic cutter system provides powerful cutting force, specially designed for complex and hard strata. It is competent for almost all inland and coastal dredging working conditions, no more limited to simple silt cleaning.

2. Pump-Boat Integrated Manufacturing, Higher Stability

As a professional pump manufacturer, we independently produce core wear-resistant dredge pumps. The pump body power, flow and head are precisely matched with the hull hydraulic system, avoiding power mismatch, idle loss and easy damage common in assembled dredgers. The overall stability and service life are greatly improved.

3. High Output & Low Operating Cost

High slurry concentration ensures effective sand and mud output, greatly shortening the project cycle. Optimized power matching reduces fuel consumption by 20% compared with peer products. Few vulnerable parts and low replacement cost help customers maximize project profits.

4. Precise Dredging & Low Water Disturbance

Adjustable dredging depth and swing amplitude realize layered precise excavation. The closed pipeline transportation avoids secondary water pollution. It can meet both heavy earth-moving engineering and ecological environmental protection dredging standards, with wide application range.

5. Modular Customization & Easy Overseas Delivery

Support fully customized size, depth, power and structure. The split modular design can be containerized, convenient for ocean transportation and fast on-site assembly. It is very suitable for overseas remote project construction.
