1. Introduction to river iron sand dredging and separating machinery

The iron sand dredging machinery is used in deep river to dredge the sand and separate the iron ore from the sand. It is a variation of the sand dredger.

The dredging depth could be from 1 meter to 17 meters, and the capacity could be as high as 120 m3 per hour.

After the river sand is dredged, the sand screen will separate the gravels/stones first. Then the sand contains iron ore go around the surface of the magnetic seprator. The iron ore, gravels, and final sand will be discharged by conveyor belt or transportation boat.

Portal frame for lifting the dredge arm


Sand screen for the separation of gravels and sand. The gravels will be discharged by conveyor belt placed aside.


Magnetic separator to recover the iron ore


After the iron ore is recovered, the sand will be washed and dewatered for construction use.
