Drum scrren bucket chain gold dredger for river mining
1. Product introduce :
Chain bucket river mining dredger is used for river gold . diamond . tin and sand iron powder so on . The bucket chain gold dredger use the buckets, driven by guide wheels on continuous rotation on the bucket bridge. sand .mud and stone so on are digged by the bucket with chain from the water above .Bucket rotates around the underwater dredging wheel, scooping up the solid in the riverbed. then into the separating system, solids larger than 10 mm will go into the tail-box, tailing discharged to place far away from gold dredger. Less than 10 mm of material from the flow channel into the Gold Sands separation system, based on the difference between the relative density of sand and gold, gold will fall into the bottom since of the high density,sand and other material will float on the surface,and discharged to the tail system by water

The dredging bucket rotates around the underwater dredging wheel, scooping up the solid in the riverbed, then trommel classifier, with single layer or double layer screens, will separate the gravels, clay balls, water plants with need sand. The find sand with fine gold & gold nuggests will be finished selection by the gold centrifuge,pulsating sluice box and fixed sluice box. After 3 process of gold panning, the gold recovery percentage can be upto 90%.
Our bucket chain gold dredger is very fir for the alluvial sand with gold. If the river sand with a lot of big pebbles, the bucket chain type is one perfect choice.
