CSD500 Heavy Duty Chinese Dredger Large Capacity 900m³ /H High Performance
product description
Cutter Suction Dredger (CSD) is one of the most widely used ships in dredging projects, mainly used for large
underwater earthwork operations such as channel dredging, port expansion, land reclamation, river silt removal,
etc. Its core feature is continuous and efficient operation, breaking up the underwater soil layer through a rotating
auger, and transporting the mud to the designated area over a long distance with a powerful mud pump.

Advantages
Continuous operation: Excavation-suction-transportation integration, with efficiency far exceeding grab/suction
dredgers
Precise leveling: The auger can control the cutting depth to achieve riverbed leveling construction
Long-distance transportation: Mud pump + relay pump can achieve ultra-long-distance displacement
Strong geological adaptability: Replacing the auger type can cope with different strata such as silt, clay, coral
rock, and weathered rock.
Core working principle
"Turning" - cutting and stirring
A giant rotating auger head covered with high-strength alloy teeth is installed at the front of the hull.
The auger rotates at high speed (the speed can be adjusted for silt, sand, and rock formations), powerfully cutting
and crushing the bottom sediments, so that they are mixed with water into high-concentration mud.
"Suction" - vacuum suction
The suction port is connected to the center or rear of the auger, which is directly connected to a high-power centrifugal
mud pump.
The mud pump generates negative pressure and instantly sucks the chopped mud into the pipeline.
"Discharge" - long-distance transportation
The mud is pressurized and transported through a sealed mud discharge pipeline, and the distance can reach tens
of kilometers.
Relying on the on-board mud pump + onshore relay pump station for pressurization, it is finally discharged to the
reclamation area (such as land reclamation block) or deep-sea mud dumping area.
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.
