Cutter Suction Mining Dredger
DREDGE MINING EQUIPMENT
Underwater mineral extraction and sludge removal with a rotating cutter head
- Dredging depth: up to 15 meters
The Cutter Suction Mining Dredger is a highly efficient water-based mining equipment. It works by rotating the cutter head, which cuts through the sediment, mixing the ore with surrounding mud and water to form a slurry. The slurry is then sucked up by a powerful mud pump through a suction pipe and is transported to the mining system onboard via a discharge pipe.
Once the slurry enters the mining system, it is typically first processed through screening equipment to remove larger impurities and gravel. Afterward, the slurry undergoes various separation methods such as gravity separation, flotation, and magnetic separation, depending on the characteristics of the ore. This helps to separate and enrich the valuable minerals from the slurry.

- Efficient Mining: The powerful cutter head is designed to break through the ore layers on the seabed quickly. The high flow rate of the mud pump enables rapid collection and transportation of large volumes of slurry, significantly enhancing mining efficiency.
- Strong Adaptability: The cutter head’s type, size, and speed can be adjusted according to different ore types and mining environments, while the mining system’s processing and parameters can also be flexibly tailored.
- Eco-friendly and Energy-efficient: Compared to traditional mining methods, the Cutter Suction Mining Dredger has a relatively minimal impact on the surrounding environment. The high degree of automation in the equipment reduces labor input and energy consumption.
