sand dredger operational principle
The jet-suction type sand pump dredger, by means of the water power, conveys the silt (or fine sand, sea sand, etc.) lifted by the water column from the high pressure gun to the destination through pipelines by the action of water pump. The dredger is novel in design, simple and convenient in operation and high in efficiency. It is suitable for dredging channel, desilting lake and reservoir, exploiting seashore, clearing port and pier, pumping sand and so on. The dredger has played an important role in cleaning silt and strengthening dyke for Yellow River.
