YUANHUA Drill-type Sand dredger
As the most efficient dredger in the sand mining field, drill type dredger rotates its drill through the mud layer
to the sand layer, digs and hits the sand layer with the high pressure water pump to make high-tensity sand-water mixture. By the high-pressure stream and sand pump centrifugal force, sand will be send to griddle
on the deck and be filtered. The sand then be delivered to stacking place by the sand delivery pump units.
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 drill-type dredger to be the most efficient and
cost-saving deep-sand-digging dredger.
Sand - Dredge- Mining- Environmental - Building - Industry -
Working depth: 0-110m
Recommended use of the environment: with rock and gravel <50% (rivers, lakes, reservoirs, ports and other sand mining
(1) Moderate size, single deck, draft less, smaller displacement.
(2) Detachable,easy to transport .
(3) Operating flexible , safety,and high efficiency.
(4) Lower cost than other dredging machine.
(5) Self-propulsion system.
(6) The thicker sand layer, the higher capacity ,operation more simple.
(7)Dredging depth : 0-110m
(9)Build in your work site.
The specifications are just for reference .We will design the machinery according to customer’s working environment .
