Product Description
Diamond Dredging Equipment River Diamond Mining Dredger
The dredger is used for dredging sand and gold mining in river. It dredges sand in the river bottom by digging bucket, transported to the trommel for screening, big stone is drain away, fine gold placer is transported to gold chute that distributed in both side of the hull gold mining.
The future of gold dredger: Set dredging, screening, mining, and tailing carriage as a whole, easy operation, low power consumption, low maintenance, suitable for a variety of river environmental gold mining operations, the recovery rate is high for gold particles.
2.Bucket chain river mining dredger structure :
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.
