How it works:
Cutter suction type: The silt is cut by the rotating reamer and then sucked in through the sludge suction pipe (high efficiency, suitable for hard soil).
Jet-suction type: Use high-pressure water jets to break up the sediment and then inhale it (suitable for loose sediment, low energy consumption).
Applicable scenarios:
The cutter suction type is used for channel dredging and land reclamation; the jet suction type is more common in shallow water areas or environmental dredging.
Efficiency comparison:
The cutter suction type has higher production capacity (up to 5000m³/h), while the jet suction type is generally ≤2000m³/h.
Reason: The cutter-suction type has stronger mechanical cutting capabilities, while the jet-suction type relies on hydraulic scouring, which has greater limitations.
The main difference between cutter suction dredgers and jet suction dredgers lies in their working methods and applicable scenarios. The cutter suction type uses a mechanical reamer to cut sediment, which is suitable for hard soil layers and is more efficient; the jet suction type relies on high-pressure water jets, which is suitable for loosening sediment and has lower energy consumption. Our store provides various cutter suction dredger models, such as JX1 and CS-1, with power ranging from 55kW to 120kW, which can meet different project needs. The specific selection needs to be determined based on the engineering soil quality and operating environment.
