100 cubic meter capacity jet suction dredger for sale

product description

The jet suction dredger is an engineering vessel that uses the principle of high-pressure jet + negative pressure suction

to extract underwater sediment. It belongs to the category of non-self-propelled dredgers. It is mainly used in river dredging,

port dredging, land reclamation and other scenes, and is especially suitable for handling fine-grained sediment (particle

size <50mm).

product parameters

The above technical parameters are for reference only,specific device configuration depends on the conditions of each

project,customer and technical requirements.

Core working principle
Jet system

The high-pressure water pump generates high-speed water flow (pressure is usually 10-20bar) and forms a jet flow

through the nozzle.

The jet impacts the riverbed to loosen and suspend the sediment, and at the same time forms a low-pressure area

behind the water pump.

Suction system

The centrifugal sand pump uses the negative pressure generated by the jet to suck the suspended sediment through

the sand suction pipe.

The mixture of sediment and water (mud concentration is usually 20-50%) is transported to the designated area through

a pipeline.

Separation/discharge

Some ship models are equipped with cyclone separators to separate sand and water on site.

When directly discharged, it is transported to a yard 1-3km away through a floating pipe.

Application
River maintenance: remove silt to restore navigation capacity (such as 5-8m water depth maintenance of inland waterways).

Dry filling engineering: extract sea sand for artificial island construction

Mineral mining: extract riverbed/seabed gold, tin sand and other minerals.

Emergency rescue: quickly dredge siltation caused by floods.
