This type of jet suction dredger is widely used in reservoir, artificial lake, river and port dredging & reclamation. The main parts of jet suction dredger is high pressure water pump and sand suction pump. One high pressure water pump will output large clear water and then clear water through the high pressure water gun flushes the river bed soil layers. Then the sludge will be sucked by the suction pipe and sand suction pump. The whole work process contains water jet and sand suction. This dredger is equipped with jigger.Its main function is used to dredge sand, select gold or diamond.

Bucket-chain gold dredgers are suitable for placer gold mining in rivers and waterways; they can be used for placer gold mining in lakes and coastal shallows; and they are employed for the re-processing of historical tailings or old mining areas to extract residual gold particles. The dredger is composed of several gravity concentrators.The concentration ratio could reach as high as 1:1000,and the recovery efficiency about 90% after series of separating.

1. The very important part of the diamond dredger is the pulsating jiggers. 2. we learn this technology from one South Africa engineer. 3. The diamond dredgers are widely used in Africa,Such as Angola, DRC Congo, Central Africa Republic,Sierre leone and many other countries.
