Introduction of Sea Sand Mining Dredger
SeCutter SuctiSand Dredging Pumpon Dredgera sand mSand DDredger Cutterredging Pumpining dredger has broad range of applications in operations the rivers and lakes for the dredging, channel excavation. In exceptional circumstances a cutter suction dredger cutter installed on the high-power devices, can be excavated without blasting rocks such as basalt and limestone strata.With characteristics of high efficiency, large output up to several thousand cubic meters per hour; the sand, or crushed rock material to rely on a strong driving force through the mud pumps and mud pipeline, pumping out a few kilometers outside.
