The jet-suction dredger is a highly efficient piece of desilting equipment-such as the Xinheng Environmental Protection brand model-featuring a downstream-flow trough design. It can handle silt with feed particle sizes ranging from 0 to 450 mm and operates with a screw rotation speed of 36 RPM. The unit features a trough slope of 12°, external dimensions of 12,000 × 3,200 × 1,500 mm, and a weight of just 10 kg; customization options are available.
A jet-suction dredger is a specialized engineering vessel that dislodges underwater sediments using high-pressure water jets and subsequently extracts the resulting slurry mixture via the suction force of a centrifugal pump. Unlike grab dredgers, which rely on mechanical grabbing, or cutter suction dredgers, which utilize a rotating cutter head, this type of vessel is defined by its "jet-suction" mechanism: it employs high-speed water jets to loosen and agitate sediment, then uses powerful vacuum suction to transport the material. This design ensures high efficiency when handling highly fluid, fine-grained sediments.
