Bucket Chain Dredger

The bucket chain dredger is based on bucket chain sand/mud dredger vessels. A bucket chain dredger is mounted with a row of chains with digging buckets fixed on the chain pieces sequentially. The bucket chains move continuously along the main rod, driven by the upper guidance wheel. When the main rod is lowered to the dredging angle, the buckets dig sediments from water bottom and transport the materials to above water surface. The gold selecting/panning vessels have equipped a set of sifting and selecting parts that following up the upper wheel for the chain. Alluvial gold can be collected through a series of selecting and sifting procedures etc.
