2.5" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other 2.5" dredges were floating on inner-tubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline 2.5" dredge sat on sturdy pontoons and used a power jet for dredge vacuum.
Production Dredging. Dredging technique in gold-bearing streambeds mainly is focused upon removing the over-sized rocks (any rock which is too large to be sucked up the suction nozzle) from the work area of the dredge-hole. In most hard-packed streambeds, this removal of the over-sized material is the bulk of the dredger's work.

Sep 03, 2015· Post by RKC onNov 24, 2012 at 3:40pm. G'day weary1, My guess would be that there will be an increase in efficiency by replacing a suction nozzle with an infinity jet, if only because a jet will be sucking up the suction hose, rather than the pushing that occurs with a suction nozzle. I'm far from convinced that an infinity jet would be any more ...
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.

Jun 09, 2015· In my opinion, if you have the option of an I-jet with a trash pump or a Dredge pump with a standard dredge nozzle, the I-Jet is the way to go. The pumps are cheaper and more readily available, you can move almost 3 times as much product for the same gas spent running and if you can get a working nozzle, you'll have almost 1/3 the start up cost.
The answer is that they each have advantages and disadvantages. The advantage of the power jet is that the operator of the dredge has to only deal with one hose when he is dredging. The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it.
For extremely shallow water conditions, a suction nozzle is recommended. Note: In order to equip this dredge with a suction nozzle, you will need to purchase the following: 1.

In the case of the power jet, for 100 GPM applied to the venturi jet, it only sucked 50 GPM through the nozzle and dredge-hose. I repeated the test 5 or 6 times and the results were always the same. The suction nozzle drew 75 GPM and the tri-jet drew 90 GPM. I expected an efficiency of 100 GPM applied to the jet and sucking 200 GPM, with a ...
Apr 16, 2014· 2 inch jet = 3.14 x (1" (radius of jet) Squared) 3.14 x (1 x 1) = 3.14 sq in for a 2" jet. 3.14 sq inches x 7% (.07) = .219 sq. Inch for eductor.

If you want to do serious excavations with a suction dredge, you must leave the opening of the suction-nozzle as large in diameter as possible, while still reducing it enough to eliminate un-necessary plug-ups inside of the suction hose or power jet. Streams, rivers and creeks in gold-bearing areas are constantly being replenished with fresh gold.
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.

Suction nozzles are suction creating devices on a gold dredge. They in effect push material through the suction hose to the sluice box. Suction tips are used in conjunction with power jets, the other type of a suction creating device used on a floating dredge.
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 140-foot 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.
The Keene gold dredge is equipped with our improved, more powerful P100 pump with an oversized pressure hose making it a more powerful dredge.
