widely used to recover materials from great depths and can also extract sand from below a clay
overburden which is also called a jet sand suction dredger. The New Sand Mining Machine is
equipped with a high-pressure water pump and a powerful sand suction pump. The water pump
can produce a high-pressure high-speed water jet to impact the bottom of the sand layer and
splash the mixed sand around the suction head, and the sand suction pump conveys the sand
to the destination through the discharge pipe.
