Product description

All DSDs are equipped with a drill pole, the suction tube and water jet tube are attached to the drill pole. during dredging,DSD vertic-
Al move down the drill pole and rotates its drill , until the drill head digs into the sand layer of  riverbed, drill pole as a spud to lock t-
He vessel into a stationary position. Then the water jet pump started, a high pressure water jet hits the sand layer to make high conce-
Ntration slurry, the slurry then pumped out of water through a suction pipe by dredge pump. The sand will be send to griddle on th-
E deck and be filtered first, after mineral recovery, the DSD will discharge the tailing materials to the disposal site via a floating pipeli-
Ne or a sand hopper barge mooring along the dredger side.this way achieves sand filtering, washing and sand long-distance delivery.
Deep-digging, filtering, washing and long distance delivering are finished in one time to make DSD to be the most efficient and cost
-saving deep-sand-digging dredger.
