Cutter suction dredger is a kind of ship that is widely used in beach dredging projects. It uses the front end of the suction pipe. The cutter suction pipe is equipped with a rotating cutter device to cut and agitate the river bottom sediment, and then through the suction pipe, the Mud, mud transport, mud unloading and other work processes can be completed continuously at one time. It is a high-efficiency, low-cost dredger and a good underwater excavating machine. The split structure makes the installation and transportation of the cutter suction boat simpler and more flexible, can be easily transported to any location. With its robust design, it is the preferred choice in its class due to low maintenance, excellent fuel consumption and high productivity levels.
Product Parameter
| Model | Dredging Capacity | Dredging Depth | Suction/Discharge Pipe Dia. | Engine(s) Power |
| CSD-200 | 500 m3 /hr | 1-5 m | 200/200 mm | 160-300 kw |
| CSD-250 | 800 m3 /hr | 1-8 m | 250/250 mm | 200-400 kw |
| CSD-300 | 1200 m3 /hr | 1-12 m | 300/300 mm | 400-600 kw |
| CSD-400 | 2200 m3 /hr | 1.5-14 m | 400/400 mm | 700-1200 kw |
| CSD-500 | 3500 m3 /hr | 1.5-15 m | 600/500 mm | 1100-1600 kw |
| CSD-650 | 5000 m3 /hr | 1.5-18 m | 650/650 mm | 2200-2500 kw |
| CSD-700 | 7000 m3 /hr | 1.5-20m | 750/700 mm | 2800-3500 kw |
Working Principle
A cutter suction dredger is positioned on spuds and anchor winches to ensure the vessel is firmly anchored during dredging. The cutter ladder is lowered. By pulling on the side wires, the cutter head is moved sideways, swinging around the main spud. The cutter suction dredger moves forward by means of the spud carriage.
The cut material together with a large quantity of water is drawn into the suction mouth. This soil and water mixture is then transported by the dredge pump through the large discharge pipeline for further transport to the designated site.
The dredged material is pumped into the floating pipelines for transport over large distances to the designated area. The dredged material can also be transported by barge.
