How does a dredge nozzle work?
The Role of the Suction Nozzle on a Gold Dredge Suction dredges utilize a high-pressure gasoline powered water pump to suck up water, gravel and gold, and inject this material into a sluice through a header box. A vacuum is created which sucks up water and gravel, pushing the material through the hose.
What kind of pump is used on a gold dredge?
