Product Description

Full Hydraulic Cutter Suction Dredger for River Hard Volcanic Rock

It is an integrated dredger featuring "cutting + suction + long-distance transportation". The core of its operation lies in the front-end cutter head, which crushes soil/gravel, and then uses a high-power dredge pump to suck it up, directly transporting it through a dredge pipe to a dump site or reclamation area located several kilometers or even tens of kilometers away.

1. Cutter Head
It is installed underwater at the bow of the ship, resembling a giant "rotating drill bit".
High-speed rotation crushes and stirs the silt, clay, sand layer, and even softer rocks underwater into mud.

2. Suction Pipe
The crushed mud is sucked in from the center of the cutter and enters the dredge pump on the ship.

3. Dredge Pump
The "heart" of the vessel generates strong negative pressure and thrust, drawing in mud and applying pressure to it.
Warmann and other heavy-duty slurry pumps are commonly used due to their wear resistance and impact resistance.

 

1	Cutter head	Powerful cutter head with replaceable alloy/rock teeth, suitable for silt, clay, sand, gravel and soft rock.
2	Pump	Adopting Australian technology - Warmann-type dredge pump, it boasts strong wear resistance, high particle passing capacity, long service life, and higher discharge efficiency.
3	Pipe	Suction hose (underwater slurry intake) + inboard hose (onboard connection) + floating hose (surface transportation) + shore hose/underwater hose (land/underwater sludge discharge) + various connectors/elbows/wear-resistant parts
4	Protal Frame	It is the most important support and lifting mechanism at the bow of a cutter suction dredger, primarily used for hanging, lifting, and positioning the cutter ladder, and bearing the huge loads brought by cutter cutting, mud suction, and water flow impact. It is a key structure that ensures dredging accuracy and operational stability.
5	Operating cabin	Integrating control, monitoring, safety, and comfort, it is responsible for centralized control and real-time monitoring of the entire vessel's power, cutterhead, dredge pump, positioning, piping, hydraulic, and electrical systems. It is the core area ensuring dredging accuracy, operational efficiency, and navigation safety.
6	Spud	The core positioning and stabilization devices of non-self-propelled or semi-self-propelled dredgers, such as cutter suction dredgers, chain bucket dredgers, and grab dredgers, are equivalent to the "two legs" of the dredger.

The equipment crushes materials through the front-end cutter head, while simultaneously pumping slurry through a dredge pump.

The slurry is then directly transported to the destination via a pipeline, achieving a continuous operation throughout the entire process of "crushing, pumping, transporting, and discharging".

It can operate 24 hours a day without interruption, significantly shortening the project cycle, especially suitable for large-scale dredging and reclamation projects.

 

Relying on high-power dredge pumps (such as Warmann heavy-duty slurry pumps) .

And a complete pipeline system (in-ship pipes + floating pipes on water + shore pipes), cutter suction dredgers can directly transport slurry to stockpile sites, hydraulic reclamation areas, or mineral processing plants located several kilometers or even tens of kilometers away, without relying on barge transfers.

This fundamentally eliminates the costs and time losses associated with barge leasing, round-trip transportation, and slurry disposal.
