8Inch Jet Suction Dredger for Sand Dredging in Channels
product description

The jet suction dredger is a highly efficient underwater dredging equipment, which is widely used in river dredging, port expansion, sea reclamation, sand mining and other projects. Its core principle is to use high-pressure water jets to impact the riverbed to liquefy the silt, and then use the negative pressure suction of the sand pump to transport the mud to the designated area. Compared with traditional mechanical dredgers, the jet suction dredger has the advantages of high operating efficiency, strong adaptability and low maintenance cost.

Working principle
Suction system: The hull is equipped with a high-power centrifugal pump to form a vacuum in the pipeline, and the mixture of silt and water (mud) is sucked in through the suction head or auger.

Auger device (key component): The rotating auger cuts and stirs the sediment on the riverbed or seabed to make it suspended for easy suction.

Transportation system: The mud is pumped to the mud discharge area (such as the reclamation area or mud transport ship) through the pipeline, and some designs can be discharged directly to the shore.

product parameters

The above technical parameters are for reference only,specific device configuration depends on the conditions of each project,customer and technical requirements.

Advantages
Efficient operation: The daily processing capacity can reach 500~3000m³, far exceeding traditional dredging ships.
Adapt to complex bottom: It can clean silt, fine sand, gravel, and even slightly cemented layers.
Low-cost operation: No complex mechanical structure, simple maintenance, and energy consumption is 30%~50% lower than mechanical type.

Environmentally friendly and controllable: Compared with cutter suction dredgers, it has less disturbance to water bodies and reduces ecological impact.

Flexible deployment: Small models can be disassembled for transportation, suitable for mountainous areas or shallow water operations.
