Sand Dredge Equipped With Horizontal Displacement Device, Cutting
Machine Lifting Device, Anchor Boom, And Deck Crane
1. Sand Dredger Work Process:
The cutter suction dredger is equipped with a submersible pump.
Place a long tube in front of the water surface with the cutter
head. The blade moves the sediment from the bottom of the lake to
the ground through the principle of rotation.
During dredging, the driver lowered the boom of the dredger to the
bottom of the lake.
Then rotate the cutter head and use your teeth to stir the mud or
other deposits at the bottom.
Use strong suction to suck the crushed sludge or sediment into the
pipeline
Then remove sludge and debris for final treatment.
This method is only suitable for cleaning lakes with relatively low
rock and hard debris content, because if the lake contains a lot of
hard debris, it will affect the rotation of the cutter head and
even damage the cutter head.
2. Sand Dredger Feature:
1. Strong adaptability. Cutter suction dredgers can be widely used
in rivers, lakes, oceans, reservoirs, etc. for sand and mud
dredging, waterway cleaning and reclamation work.
2. High efficiency. The cutter suction dredger can dredge and
discharge sand at the same time, without the need for other vessels
to transport.
3. Easy operation. With the help of hydraulic system and PLC
control system, all dredger operations can be completed in the
operation room.
4. The dredger is detachable. Therefore, they can be easily
disassembled and assembled.
5. Can be customized according to customer's project requirements.
7. The dredger will use the best parts, such as the world famous
Cummins engine or engine, Siemens PLC control system.
8. Professional engineers will be sent to the project site to
require customers to install, debug, test and train operators of
dredgers.
