How to choose the dredging equipment?On the market there are all sorts of sand pumping equipment(Dredger), such as: the traditional chain bucket sand-excavating dredger, large junk shot suction dredger, drag type sand pumping dredger, drilling type dredger, self-sucking/dumping dredger, but how to choose to the one that fit your sand bed condition? Let's explain how to use all kinds of sand pumping dredger.

(1).Chain bucket dredger: river channel sand and gravel diameter is larger, sand layer is shallow can be used chain bucket dredger. Advantages: low cost and easy maintenance. Disadvantages: low production

(2) Large junk shot suction dredger: good sand layer, easy to collapse, soft stone content and less than 10cm in diameter. Can be used to shoot suction sand pumping ship, equipment price is medium, higher output.

(3) Drag type sand pumping dredger: the bottom of the river sediment is hard, there is mud layer. Wring suction sand dredger can be used. Wring suction sand dredger has a wide application range and can be used for dredging, dredging, dredging and so on. The price is relatively high, but the output is high and the cost performance is relatively high.

(4) Drilling type dredger: the sand layer is more than 20 meters away from the water surface, can be used drilling sand pumping ship, this equipment pumping sand depth is higher up to 60 meters.

(5) Self-sucking/dumping dredger: the location of sand pumping is far away from the shore, the equipment can be used to directly carry the sand to the shore, through the bottom of the ship door to unload, in a small cutting boat will pump the sand to the shore.
