When was the last time you saw a 4″ gold nugget? Most of us take a stick, or beat on the sides of the hose, but all that does is put undue stress and strain on the hose. Did you know whenever you have to shove a stick down your hose or beat on your hose to clear a jam, you are shortening the life of your suction hose? Brother, have you priced the cost of suction hose lately? It ain’t cheap! The main cause of clogs are, when a slower moving larger rock gets wedged by a faster moving smaller rock against the sidewall of your hose. Its unique design will classify the debris and allow the user to use its pointed nose to loosen the rocks and get at the gold!Īn added benefit. This classifier will fit onto the end of your dredging nozzle. Sorry the site will not let me attach a picture of the suction nozzle.MEO (Mining Equipment of Oregon) MEO Bullet Gold Dredge Nozzle Classifiers are one of a kind. I have a Honda GX engine driving a Koshin pump which will deliver 240 GPM.īeing a commercial diver I have always used large diameter underwater air lifts supplied with large compressors which move massive amounts of sea bed, I am hoping this dredge will move a decent amount of material. I am thinking of a 4 inch suction pipe supplied from a 2 inch pressure hose same as in the photo but I am wondering will I have to reduce the diameter of the pressure pipe as it enters the suction pipe, I am sure I have read somewhere that the reduction should be approx times 4 so that would make the reduction diameter at 1/2 inch as it joins the suction hose. So I am looking at getting one made from a local blacksmiths at short notice. First post on this very interesting and informative site, I'm looking for a some advice from the experienced dredging people on this site, I am from England and am looking to remove a considerable amount of sand and small pebbles/rocks from the seabed at approx 30ft depth, I was looking at buying a 4 inch suction nozzle from an ebay site based in the USA (photo below) but as this job will be coming up in the next week, the delivery time is too long.
