Hi All
I am lookin for a small dry blower with a small motor and a bellows. New or second hand. Have seen the Keene machine and wondering if any other machines are still in existence.
Want to be able to put it in the back of my ute--I have access to a larger dryblower but lookin for something small.

Regards

Hi Oneday,

I saw one recently at Miners Den in Mitcham Vic, it would easily fit into a ute. Give them a call or go online??

Try Miners Den in Adelaide, he sells a dry blower called the Dynamic force, made in the USA and under $1000, saw a demo and it seemed to work very well. Mallee00 and the mutt

If you have access to the big job, I recommend going with that! You will have a hard time retrieving any fine gold with the small unit?
Remember gold isn't 19 X heavier out of water? Small gold flakes "Bye Bye".
"Thats not dandruff, thats gold"?? & if you've been at it for a couple of days, don't forget to pan "your waste"????????????????

Hi Someday

I didnt want to be that conspicuous with the big gear--all up we would have to load a 40' trailer and drag all that gear into the bush - then hope that no one sets fire to the gear- unfortunately we do have a few assholes up here too.
I dont mind leaving a bit for someone else.
Karratha is a big place and 20mins you can be digging gold.

Still lookin
Regards

Next best option then, Is build your own! The prospector shops are there for one thing, your $ ?
I wish I paid more attention over in WA! Saw a couple of dry blowers that fitted on 8x5 trailers! To me that was fairly serious.

I use a hand made puffer, 12 volt it's made of wood (timber) it folds flat and weighs 20 lbs. $400 Ol' Yeller
It captures very fine gold. And is very quiet.

Metal detectors and a drywasher go hand in hand.

I've seen one of these in action "The Gold Exorcist" and it worked very well, small and very portable. The one I saw in acton was purchased from Coilteck at Maryborough in VIC for somewhere around $900 I think?

Here is a link to a bit of info on it.

dry blowers old or new Original
The Keene Dry Washer model 140

You may want to take a look at the Keene 140 model Electrostatic Dry Washer. It's portable, lightweight and can easily be setup by a single person with ease. An added benefit if the 140 model is that the blower can be reversed and it can be used to vacuum gold from crevices and dry surfaces.
The next model up is the 151 model Electrostatic Dry Washer which uses a Honda motor and is considerably bulkier... making it a little harder to setup by an individual operator (not impossible, just harder and the motor is larger much heaver). You can shovel a LOT of material through them and the machine classifies as you go but the soil needs to be quite dry for the machines to work properly. The benefit of this model is that the Honda motor produces much more heat which aids in both drying the soil further and by effectively charging the gold in an electrostatic manner. I have one of these models myself but feel that the 140 model would have been a better choice due to reduced bulk and ease of use. There's a 140 Keene Dry Washer at the Miner's Den NSW (not a plug, they just happen to have one) at the moment.


The new Coiltek mini-Dry Washer is designed for classified or fine materials. It's a great portable unit that is surprisingly small but the soil fed into it will need to be classified first for best results. There's a video that I edited on the subject of this machine that you can watch on YouTube:



All the above models work via generating an electrostatic charge on the synthetic mat on the riffle tray. This attracts gold (especially fine gold) to the tray. Heavier nuggetty bits will get caught on the riffles.

The "Dynamic Force Dry Blower" by Coiltek Manufacturing seems to be the same as the "The Gold Exorcist"

Oneday69,
Here is bellows type dry blower I built powered by a 3.5 hp Briggs & Stratton.
This machine worked a treat and the fines were separated using a home built sluice with a 12V bilge pump that recirculated the water.
