What is a dredge in mining?
Dredging is the underwater excavation of a placer deposit by
floating equipment. Dredging systems are classified as mechanical
or hydraulic, depending on the method of material transport. The
bucket-ladder, or bucket-line, dredge has been the traditional
placer-mining tool, and it is still the most flexible method for
dredging under varying conditions. It consists of a single hull
supporting an excavating and lifting mechanism, beneficiation
circuits, and waste-disposal systems. The excavation equipment
consists of an endless chain of open buckets that travel around a
truss or ladder.
Main Features of gold mining dredge
1) The machinery has strong geographical environment adaptability,
simple structure, easy maintenance.
2) It is an ideal machine of dig sand and the river dredging.
3) It can be used for mining salt ponds, offshore rivers dredging,
hard bed mining and channel improvement development.
4) It has many advantages such as reliable performance , long life,
low cost and large working(500-3000 cubic meters / day).
5) Digging sand separated by screening sandy is pure, no
impurities, it is the ideal sand of construction industry, cement
pre-operation.
