How to choose a suitable Cutter Suction Dredger?
Cutter Suction Dredger Working Principle
The cut slurry (cut material together with a large quantity of water) is drawn into the suction mouth. This soil and water mixture is then transported to the designated site by the dredge pump through the floating discharge pipelines.The dredged material can also be transported by barge.
HID cutter suction dredger( CSD) is positioned on spuds and anchor winches to ensure the dredger vessel is firmly anchored during dredging.
The cutter bridge ladder is lowered. By pulling on the side wires, the cutter head is moved sideways, swinging around the main spud.The cutter suction dredger moves forward by means of the spud carriage.
1.--HID Cutter Suction Sand Dredger, the dredger size is from 6 Inches to 32Inches.
The model is depending on the discharge pump size and the water flow is from 500 m3 /h- 8000 m3 /h.
2.--HID Cutter Suction Dredger can be used in River, Coastal, Reservoir, and Lake Function and use: Desilting, Broaden river for ship navigation, land reclamation, scours, blows fill project. Suitable for dredging river clay, mud, and coastal deposits.
To recommend the most suitable dredger and quote you a price, we need check below information with you:
1).--Dredging Depth(Meters).
The standard dredging depth of HID cutter suction dredger is below 1.0m - 14.0m (underwater).The more dredging depth, the larger of the main dredge pontoon size. The more required dredging depth, the less solid cutter suction dredger can suction(the solids concentration is lower).
The additional submerged pump is needed for increased solids density purpose.
2).--Max Discharging / Transport Distance (Meters).
The transport distance refers to the demand max horizontal distance that from the dredging site to the designated area with the pipeline.The longer discharge distance, the greater of the sand pump power installed.
The standard discharging distance range is 100m-4000m. Pump booster is needed if a longer discharging distance is requested.
3).--Production Capacity(m3/ h)
The production capacity of cutter suction dredger is equaled to Slurry Flow Capacity(m3/ h) *Solids Density(10%-25%).
4).--Type of Soil to be dredged.
The type of soil to be dredged has a strong influence on the installed cutter head and side winch power, the strength of ladder, pontoon, and spuds.
