3. Product Feature And Application

1) The hydraulic head 12inch river sand csd dredger is widely used for mining, sand production, reclamation construction, desiliting, land reclamation and so on.

2) The dredging, conveying and discharging process can be finished continuously.

3) It is highly efficient with low cost, a good underwater dredging machine


4. Product Details


The hydraulic head 12inch river sand csd dredger power system is consisted of diesel engine, gear box and hydraulic transfer gear box. The dredging pump system and hydraulic system are two different independent systems. The hydraulic system requires the engine works at fixed speed with stable output power. The main engine speed will be adjusted time to time based on the power of dredging pump system, which is changed with the concentration and discharge distance of the pumping liquid.


 The hydraulic system is made up of hydraulic oil tank, control cabinet, oil pump, valve block, hydraulic winches, cutter devices and auxiliary hydraulic equipments.
