10-inch suction sand pumping boat dredged 10 meters deep for small rivers
Product description
A sand pumping ship (also called a sand suction ship or dredger) is a special operation ship used for underwater sand
mining, river dredging, land reclamation and other projects. It extracts the underwater sand mixture through a powerful
pumping system and transports it to a designated location. It is widely used in water conservancy projects, port construction,
mineral mining and other fields.

project,customer and technical requirements.
Working Principle
The core of the sand pumping ship is the "sand suction pump + pipeline transportation" system
Broken mud layer: The bow is equipped with a high-pressure water gun or a rotary auger to break up the compacted sand layer on
the riverbed/seabed into flowing mud.
Pumping mud: The centrifugal mud pump generates negative pressure and extracts a mixture of mud and water (mud concentration
is usually 20%-40%) through a sand suction pipe extending into the bottom of the water.
Pipeline transportation: The mud is transported to the shore yard, sand transport ship or reclamation area through the sand discharge
pipeline, and the transportation distance can reach several kilometers (relay pump pressure is required).
Separation of mud and sand: The end is separated by a vibrating screen, cyclone or natural sedimentation to separate sand (construction
sand) and silt (for land reclamation or abandonment).
Application
River/port dredging: remove silt to ensure smooth waterways
Reservoir desilting: prevent siltation and extend the life of reservoirs
Sand mining: mining of sand for construction
Land reclamation: land reclamation by filling, such as coastal development zone construction
