30 / 32 inch 750 mm output capacity large hydraulic cutter suction dredger
Cutter Suction Dredger(CSD) is the most widely used engineering ship in dredging works and sand production. The rotary cutter head at the inlet of the suction pipe cuts and loosens the sand/mud layer to form sand-water mixture of a certain consistency. The pump uses its centrifugal force to suck the mixture and then transport it to the depository through the discharge pipe. The digging and transporting are progressing at the same time. CSD is of ideal dredging depth, long discharge distance, high efficiency and low cost.
The suction tube has at its end a hydraulically operated cutting wheel that cuts the hard sea bed into small chunks of rock and spoil. The size of the associated cutters depends on the hardness factor of the sea bed. The cutter units have a high pressure nozzle at their centre and this is used to agitate the cut spoil. The spoil is then normally lifted using an ejector system from the main pump through the suction pipe, so the hard spoil does not go through the moving parts of the pumps.

Most CSDs are barges that are towed to the required areas and are anchored or spudded to the sea bed. Spuds are used, since the loads on the cutter at nozzle length are high and the spuds keep the vessel from moving whilst dredging. These spuds are heavy pike-like structures which can be dropped into the sea bed by the dredger.
Cutter suction dredgers are used to deepen harbour berths or channels and areas where the sea bed is harder than normal and where a suction dredger cannot lift the required spoil. The dredger literally cuts the hard materials and rock away from the sea bed and sucks it through the cutter suction pipe. This is then discharged ashore or to barges for spoil removal.
