submersible sand suction dredger

Sand mining machine , dismoutable suction dreger machinery

Suction dredger is currently the sand dredging projects, collecting sand industry in using the most flexible convenient work ship.It is the use of pump suction principles through straws ends water cannons spewing out water cannons to bottom sediment impact and the formation of certain concentration mixture,Then by centrifugal pump of blending materials to be delivered through the row tube to accumulation point.The boat equipment, complete floating bodies deft, facilitate transportation, is a kind of high efficiency, low cost of sand mining ship. Is a good sand equipment, for first-time investors trial and investment.

Dismountable sand suction dredger consists of three pontoons: one main pontoon and two side pontoons. The pontoons are connected by the connecting pieces and tightened by high intensity bolts and nuts.

This ship all equipment design for diesel engine drive .

Application: sand suction and dredging projects at near shore, in lakes, reservoir and harbor.
