The main components of the jet suction dredger include one high pressure water pump and one sand pump. The high pressure water pump impinges the water through the high pressure water gun to bottom sediment layer, and the sediment splatters around the suction head, pumped by the sand suction pump through the suction pipe to the designated position. That water spray processing and pump suction process will complete the entire dredging process. This type dredger is widely applied for dredging projects locates in reservoirs, artificial lakes,rivers, ports and sand mining projects.
