High gold recovery 250m3/hour bucket chain gold dredger for
alluvial gold mining
1.Introduction of gold dredger
The draft of bucket chain type gold dredger is usually less than 1
meters. So it is very easy for them to get enough floating force to
work in the water. When it starts to work, The operators will
slowly lay the dredging arms down into the water to some depth.
The dredging bucket rotates around the underwater 4-angle wheel,
scooping up the solid in the riverbed, then dumping the sand into
the classifying trommel which will be covered with single layer or double layer screens.The classifying screen
will separate the gravels, clay balls, grass and branches off the
sand. The sand with fine gold & gold nuggests will be finished
selection by the pulsating sluice box and fixed sluice box( which
is equipped with gold catching grass and gold catching carpet .
After 2 process of gold panning, the gold recovery percentage can
be upto 90%.
We suggest the clients to think about purchasing shaking table and
gold smelting furnace for further selection.

and successful products. They are widely exported to and used in
Russia,Mongolia,Indonesia, Ecuador,Central Africa and other
