Drill-type Sand dredger
Drill type sand dredger currently is the most efficient equipment for sand mining , it is mainly for dredging underwater sand mining through the thick mud layer . by rotating the drill head to drill through the mud layer to the target sand layer, assisted by high-pressure water pump, to carry out the rotary sand. According to working environment ,we can design drill-type dredger, as 10~16 inch , 15-110m dredging depth, capacity 200~1200m³/h .
Drill type sand dredger can dreging sand underwater more than 110 meters through the thick mud floors to the target sand layer specially in lakes, reservoirs and sand areas.
Our company produces drill type dredger: high capacity,digging deeper,lower cost,easy to operate and build in yourworksite. Drilling-type dredger digging depth over 110m , capacity200-1200m³ / h.
Drilling type dredger also pumped underwater sand from the sand layer in river by suction pump, and discharge to the point place.
This machinery suit for lakes ,rivers ,ports, artificial lake and sand dredging .
New design ,easy to operate ,high capacity,use for channel dredge ,port cleaning ,sand process etc .
The equipment consists of the hull, conveyor systems, water systems, evacuation systems and other components, including the power delivery system, clutch, mud pump etc. Evacuation system comprises a high pressure pump, vacuum devices.
