Product Overview

The double power siphon gold dredger is a core upgraded equipment for underwater placer gold mining, equipped with main and auxiliary dual diesel power systems, integrating siphon sand suction, high-frequency screening, gravity gold separation and tail water purification integrated functions. It is specially designed for complex underwater placer gold mining scenarios such as rivers, river beaches, mud flats and reservoir shallow banks. Relying on the negative pressure siphon principle, it can deeply extract placer gold raw materials 2-5 meters underwater without large excavation devices. The shallow draft pontoon hull will not sink the ship or damage the river bed. The dual power outputs synergistically, supporting 24-hour uninterrupted operation. In emergency scenarios, the single power can operate independently, completely avoiding work delay caused by power failure. The whole process is automatically operated and can be controlled by a single person, which is an efficient tool for large-scale mining of small and medium-sized underwater placer gold.

Applicable Scenarios & Materials

Large-scale gold panning in rivers/river beaches: Placer gold mining in shallow water areas of rivers and alluvial layers of river beaches, suitable for 24-hour continuous operation
Gold panning in complex water areas: Muddy thick tidal flats, shallow rapid rivers, swamps and other water areas where conventional equipment is difficult to operate
Re-mining of reservoirs/lakes: Deep extraction of residual placer gold in old mining areas of reservoir shallow banks and lake beaches to tap residual value
Gold panning in remote water areas: Remote water mining sites without external power supply and inconvenient supply, dual power without frequent refueling
