General description of bucket chain dredger
The bucket ladder dredger is one of the mechanical dredgers. A
bucket dredger is a stationary dredger that is equipped with a
continuous chain of buckets, which are carried through a structure,
the ladder. As a kind of mining equipment, as long as it is used
for the mining of gold and diamonds.
How does the bucket ladder dredger for gold and diamond dredging?
During dredging, the dredger swings round the bow anchor by taking
in or paying out the winches on board. The buckets, which are
filled on the underside, are emptied on the upper side by tipping
their contents into a chute along which the dredged material can
slide into the barges moored alongside.
The chain is driven by the so called upper tumbler at top of ladder
frame, which is connected either via a belt to the diesel or
directly to an electro motor or hydro-motor.
Area of application
Bucket dredgers are only used in new or maintenance dredging
projects when the initial depth of the area to be dredged is too
shallow for trailing suction hopper dredgers and the distances
involved are too long for hydraulic transport. For environmental
projects, which require the dredging of ‘in situ densities’, the
bucket dredger is suitable peace of equipment. When dredging for
construction materials such as sand and gravel, or for minerals
such as gold and tin ores, bucket dredgers are still frequently
used.
