New Diesel power Jet Dredger with Gearbox

product description

Jet Suction Dredger is a highly efficient and low-cost dredging equipment, especially suitable for dredging soft silt, and

has unique advantages in environmental protection projects and shallow water areas. However, for hard bottom or deep

water operations, it is still necessary to rely on Cutter Suction Dredger (CSD) or other heavy dredging equipment.

 product parameters

Core components
High-pressure water pump & injection system
High-pressure water pump generates high-speed water flow, which is sprayed onto the riverbed through the nozzle to

suspend the silt.
The injection angle and pressure are adjustable to suit different soil types.
Sludge suction pipe & mud pump system
The negative pressure mud suction pipe sucks the suspended mud and transports it to the mud discharge area through

 the mud pump.
Sludge discharge system
The mud is transported to the reclamation area or mud transport ship through the pipeline. Some models support long-

distance transportation.
Positioning and movement system
Usually, anchor positioning or small propellers are used to adjust the position, which is suitable for shallow water operations.
 Workflow
High-pressure water jet flushing: The nozzle sprays high-speed water flow to loosen and suspend the silt.
Mud suction: The mud suction pipe sucks the mud-water mixture under the action of the mud pump.
Mud discharge: It is transported to the designated area (such as the reclamation area or mud transport ship) through

the mud discharge pipe.
Hull movement: The working position is adjusted by anchor cables or propellers to achieve continuous dredging.

Applications
River dredging: remove silt from rivers and canals to restore navigation capacity.

Lake management: clean up eutrophic sediments and improve water quality (such as urban landscape lakes).

Port maintenance: dredge loose sediments in harbors and anchorages.

Environmental protection engineering: low-disturbance dredging to reduce the impact on aquatic ecology.

Mining assistance: extract sand ores (such as gold sand and tin sand) from the seabed or riverbed.
