Inspired by Goldigg's excellent build and others on the forum I have decided to build an old style bellows puffer dry washer rather than a leaf blower version as I can't stand the noise of the leaf blower versions and I want to be able to operate it by a small electric motor off my troopy's secondary battery or by hand crank if that runs down ...
Drywashers are an excellent tool to recover gold from dry material. Because the nature of the material can vary widely from fine dust to gravel and the gold being recovered can vary in size from chunks to very small pieces the size of face powder a drywasher can be configured to maximize the recovery rate in any circumstance.
Royal Gold has a 10" x 24" Recovery Box and is 47" tall which is the proper working height. Total weight is 27.75 lbs. Hopper adjusts to 3 feeding angles to accommodate different types of materials. Combination Riffles laser cut from a single piece of steel for enhanced recovery. Baffled first Riffle to ensure even air pressure to prevent ...
The main thing to remember is that the machine needs to separate the gold from the lighter, valueless materials. If you only have a small amount of air-flow running through your dry-washer, then you will need more pitch on the recovery system-and you may need to feed the material slower. Too much air flow can also be a problem.
In order longest (least efficient) to shortest: Panning: 42 hrs, Metal Detecting: 40 hrs, Sluicing/Highbanking: 30 hrs, Dry Washing: 30 hrs, Dredging: 20 hrs, Hard Rock Mining: 8 hrs. I think it's worth emphasizing that this is a time efficiency, not a cost efficiency. Panning is clearly the least expensive with hard rock mining by far the most.
Drywashers are operated by shoveling gold-bearing gravels into an upper box which is covered with a screen. The larger rocks that are too big to pass through the screen slide off. Gravel small enough to go through is fed down into the lower gold recovery box, which is an inclined trough with cross riffles much like a sluice.
Most blokes here in WA do with the right geo conditions on finer gold like to run their "Puff Puff's" on 60 - 90 Puffs a minute. What sort of speeds do a few of yous like to run the small 3x1 ft puffers. We now have water rights to pump from a large ex mine pit and scrape to …
This video is a test of a home made manually lever operated gold dry washer. After testing the dry washer at home I made several modifications, including enl...
Dign4au2, RSJ knew the gold guru and his drywashers are by far the best I've ever used. My partner, Doc, has 2 Critenton drywashers, and he has found alot of gold. Doc was Dowie's partner for several years, up until he passed away.
On my drywashers I try to run as flat as possible and only use enough RPM on the blower to keep the bed fluid and moving. I also added which some drywashers already have it is a blind under the riffle so once a piece of gold gets into the bottom part of the riffle it receives less turbulence and less chance to be pushed up to the top of the dry fluid flow.
A puffer is easier to set up as well. I often fold mine down and put it and a small motorcycle battery in the backpack and walk into areas that most guys won't make at least to trips to get their blowers into. Another thing, less dust with a puffer. I'm not into whearing a dust mask all day. I absolutely love my desert wolf dry washers.
I am just few months short of getting a drywasher.. however I am hung up on the one to get that would suit my needs.. I have read great reviews on the keene 140s as well as the 191/161.. but I am more focused on the 140s and 161 for the light weight..or the compact fold up of the 140s..

The dry washer is merely a tool for finding gold. You are the one who has to find a spot that has the productive gold bearing gravel. As with other prospecting tools, the dry washer is not that difficult to learn to operate, the difficulty is in finding paying deposits of gold bearing gravels.

A number of small, hand-powered machines are on the market and most work quite well within certain limits common to all dry washers used in gold mining. First, consider two identical gold particles, one in a dry washer and the other submerged in water.
A dry washer is a piece of equipment that is used to separate gold from sand with pulsations of air coming up through a porous cloth medium. This allows the gold to settle downward and get caught. It is the gold prospecting equipment of choice in dry desert areas. The vibrations and flow of air replace the function of water in the normal sluice ...

1) I would like to know what is the smallest approx.~mesh sizes of gold that the Keene 151 or 140 dry washer will capture in what approx.~percentages?----- [Just for an hypothetical example to give you an idea what kind of information I want, the size of gold captured like about ~95% at (1/8")8 mesh, and ~50% at (1/16")16 mesh.]. 2) What small size of gold do dry washers lose over the end, …
Vibrations and bursts of air help put the gold and other deposits in the dredge riffles, providing a fast, efficient way to sort small gold pieces out of sand and sediment. While the function of gold drywashers is the same, the mechanics of the machines can vary largely.
Why am I using a drywasher & how small in mesh gold am I wanting to capture? And allow to blow by? Doing such should answer a LOT of questions. Personally, I'd go with the Keene 140s + weed-blower + gallon of fuel + 6' to 8' of air hose + a small collection of quality breathing masks + ear protection. Even eye protection, bandanna & wide-brim hat.
Keene's New large dry washer 210 series. This is our latest test on the new commercial large scale dry washer.

Using a dry washer is a great way to find gold in many areas in the southwest. Limited water makes gold prospecting difficult in many regions, making common mining methods like panning, sluicing, and dredging impossible. They are a great way to find gold in …

Many club members use a dry washer and you can see quite a variety at the outings. Jack and Gene even found some gold with the small battery powered dry washer shown here. Some manual dry washers can be easily converted to electric. Oddly enough, the desert is too damp for dry washing much of the year, especially as you dig down towards bedrock.
Small modern drywashers actually work quite well though and there are many areas to drywash for gold across the desert southwest. Drywashing is less efficient than wet methods such as sluicing and dredging, at least for fine gold. Also, gold deposits in desert areas tend to be less concentrated than in areas with seasonal streams and rivers.

Even today, some dry washers have trouble recovering gold after the top layer of dry sand has been removed, due to the moist sand and gravel below the surface. New technological improvements allow modern units such as the 151 drywasher model made by Keene to help dry out this material and increase gold recovery to very high levels.
A dry washer separates gold from sand by pulsations of air coming up through a porous cloth medium. It is the gold prospecting equipment of choice in desert areas. The vibrations and flow of air replace the function of water in the normal sluice, allowing the gold nuggets to settle downward.
Most dry-washers will run this material, but the efficiency will be diminished somewhat. If the ball stays intact or breaks into two or three parts, the pay-dirt must be dried before running through the dry-washer. On a good day, most dry-washers will lose between 10% and 20% of the finer-sized gold which remains trapped in small dirt balls.
The Drywasher . A device known as a drywasher (also sometimes called a dry blower or Mexican jig) was the tool of choice for the early desert miner. They were the perfect piece of mining equipment for the individual miner to work isolated desert gold placers far from any existing water.
