Feb 11, 2018· My buddy does the electric dredge and does quite well. he bought a nozzle but I don''t know how he gets the suction from the nozzle to the header box.

The size of a gold dredge ( inch, 2 inch, etc.) is determined by the diameter of the suction hose— the larger diameter the hose, the more material can be processed. A floating gold dredge is essentially a floating sluicebox that uses an engine and pump to create a vacuum and send gravel (hopefully goldbearing gravel!) into the sluice box ...
Jun 13, 2018· A suction gold dredge is basically an underwater vacuum cleaner. Material is transported from underwater to the surface and run through a sluice box to capture the gold. A sluice box works because gold is 15 times heavier than sand and gravel and so is easily trapped by the riffles and carpet in the sluice box.

The Proline was the first 2" dredge with this feature. Due to recent changes in the pump and jetting system on this dredge, the suction power has dramatically increased. This increase in power led to a new classifier with a riffle system that produces a more effective low pressure vortex behind the riffles themselves, improving fine gold recovery.

In the case of the power jet, for 100 GPM applied to the venturi jet, it only sucked 50 GPM through the nozzle and dredse. I repeated the test 5 or 6 times and the results were always the same.

In any dredge, you will have 2 types of suction devices; either a suction nozzle or a power jet. A suction nozzle only works with higher pressure pumps. The recommendation is a minimum of 140foot head lift for a suction nozzle. A power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.
I used the basic straight jet venturi as the baseline and compared it to the trijet, the suction nozzle and the infinity jet. The infinity jet produced the most vacuum, the trijet was 2nd, the suction nozzle was 3rd, the straight jet came in last in performance. There are some strange dynamics going on .

The suction dredge was much smaller then the floating barges and requires far less equipment. The suction dredge required only a centrifugal pump and gas motor, a float pontoon system, a sluice box, a venturi jet generator, a dredge hose, and a nozzle. This discussion involves the venturi jet generator that provides the suction for the dredge ...
The stainless steel nozzle supplied with the AP dredge was too bulky for my intended area. Most gold is in rather shallow water, deep inside the thousands of crevices. The gold source is about 300 meters upstream from the hills. This 1 km stretch of river has been heavily prospected. My first task was to build a functional venturi or infinity jet.
