Product Description

1. Introduction of Cutter suction dredger MST-CSD250


Defination:  A cutter suction dredger is a hydraulic dredger that uses centrifugal pumps with a rotating cutter head to loosen, lift and transport dredged material. MST Dredging machines are non-propelled dredger. 
Cutter suction dredger MST-CSD250 has the ability to dredge both soft and hard materials under water. It is mostly used for dredging sand or other materials from rivers, lakes, dams, ports and ponds for some construction materials. Also it always work together with sand processing system for get new use of sand.

Working method: The cutter will be moored with spuds or anchors while at work so that in essence the dredging operation takes place with the cutter in a stationary position.

Project Applications:  Cutter suction dredgers are used wherever the seabed is hard rock. They are used for larger dredging projects such as navigation channels and port development and maintenance and land reclamation and in major projects such as the Panama Canal and the Suez Canal.

Types of dredging materials: Cutters are powerful and are capable of dredging all kinds of material in water including hard rock.

They are able to effectively dredge:
silts,
clays,
sand,
gravel,
cobbles,
fractured rocks
and sound (unfractured) rocks.

Advantage: 

The primary advantage of a CSD is that it is able to dredge hard materials that most trailing suction hopper dredgers cannot handle.
