product description

The cutter suction dredger is a continuous dredging equipment that integrates excavation and transportation.

Core working principle:

Excavation: A large rotatable cutter head is equipped at the front of the hull. The cutter head is usually made of

high-strength alloy steel with sharp teeth or blades. It is lowered to the area on the bottom of the water that needs

to be dredged, and is driven to rotate by powerful power to cut, crush and loosen the mud, clay, gravel and even

soft rock on the bottom of the water.

Suction: A mud suction port is installed in the center of the cutter head or just behind it. A powerful centrifugal mud

pump (usually located inside the hull) generates a high negative pressure (vacuum) at the mud suction port.

Transportation: The material broken and loosened by the cutter is mixed with water to form mud (mud-water mixture),

which is sucked in through the mud suction pipe under the suction force generated by the mud pump. The mud is

then transported to a designated location (such as a mud discharge area or a reclamation area) several kilometers

or even more than ten kilometers away through a mud discharge pipe (which can be a pipe on a ship, or a floating

pipe or submersible pipe extending to the shore or a designated area).

product parameters

Technical features
Efficient and continuous operation: The cutter suction dredger can work 24 hours a day, and its efficiency

is far higher than that of grab or chain bucket dredgers.

Adapt to complex geology: By replacing the auger head, it can cope with soil layers of different hardness

and even break rocks.

Environmental protection: It can control the spread of mud and reduce the impact on the water ecology.

High degree of automation: Modern ships are equipped with intelligent control systems to monitor dredging

depth, concentration and other parameters in real time.
