A Devil Of A Device Ready To Test Next Month

[RM Outback]

Stupid question (as most of mind tend to be while in lockdown) but isn't this just a Creswell Mini Gold Extractor/Rotapan turned on an angle? Not the unit but the theory, gold heavy to bottom, lighter stuff on top and out of here.

Think the Creswell/Rotapan does almost the same thing albeit in a slightly different way (yes I know most people use the Creswell/Rotapan with water) but provided the material was totally dry (as it also needs to be with the Jackwinder) then the heavies (gold) should collect in the bottom pan displacing the lighter stuff which falls into to bucket.

MGC/Rotapan would catch it in the centre bottom pan while the Jackwinder catches it on the angle .... both seem to rely on the lighter stuff being "siphoned off" (by going over the lip with the Rotapan, or out the "exits" on the Jackwinder.

For Volume the Jackwinder would clearly be better but for small scale testing the Rotapan might be OK. In Victoria obviously we CAN use powered dryblowers so that would always be my 1st choice down here.

Will have to wait till i'm freed from lockdown but will certainly try/test it out as a dry washing unit.

In principle it is the same, same as all gold recovery systems principally relying on heavy materials being separated from the lighter materials. I'm not in a position to qualify the operating technique. Outback has said the video is on hold due to the manufacture dealing with medical issues. I'm sure Jack will elaborate and provide the video and answers when the time is right. It definitely isn't the same as the Creswell unit it is however genuinely unique and worthy of consideration. I'm hoping to put some dirt through mine on the weekend, I'll post results when I do :beer:

Agree RM Outback especially if talking high volume throughput... the Jackwinder wins hands down and regardless of whether it's sluicing, highbanking, dry blowing or whatever it's volume throughput that counts.
Just for curiosity it will be interesting to see how much the Rotapan type setup retains when run "dry".
Look forward, as no doubt are others to see how your new unit goes ..... good dirt should give good results good luck.
Cheers T.

Hi all ,
The JackWinder works different to all outher pass or present gold dry concentrators .
It traps the gold quicker with better retention .

How it works ? after 7 years & huge amounts of hours experimenting with different designs I'm not going into the technical side but every part of today's JackWinder has been made to work better then my previous designs .

Those who are interested but no sure should wait for the reviews & video

Cheers & Beers
Jack :beer:

Back in 2014 ' this was the best unit I had come up with , yep it worked OK .
But compared with today's JackWinder - it was primitive , with another 6 years of non stop designs & development I've got the best ever unit ever !

Latest version definitely on the shopping list, but going to hold off until we can start travelling once all the restrictions are lifted. Feeling a bit like a caged rat right now as are many others.

Hi jack. Does the dirt you put into the jackwinder need classifying first? Or does it automatically break up dirt clods and remove larger rocks?

 

[hippyhunter]

All good jack i found it earlier in the thread.
Classify to 1/4" or 6mm.
Do you reckon it would loose gold if u didnt classify and just hand removed rocks larger than the exit holes?

You need to sieve down to half inch in order for the winder to work as designed ' quarter inch is better , that way you will then be running a lot more material
through for more gold !

Hey Jack, How did you prevent the Brazil nut effect?

We need a jack sievewinder now to make classifying easier
I noticed you had such an attachment built in to one of the earlier models. Was that removed for weight reasons or did it mess with the process?

That still happens but it's not dentrimental

Just make your own with some mesh !

I removed the classifier in later designs because it was easier & more efficient to just use a sieve .

This is my half inch sieve , fits nicely in the bucket :

I have a homemade bucket sieve. I need to work out something a bit less strenuous though. Your system looks easier than mine. Will work something out eventuallly i guess

Silly question ... does it even come into play where the density, gold v misc. stone/mineral matter are so different?

Looking forward to review/seeing how it goes ...

Cheers T.

Add me to the list please jack. Cheers :Y:

Find that an interesting answer Jack, as using a sieve adds a primary process and additional equipment. Would have thought transferring from shovel direct into the winder or via bucket would be more efficient, particularly if you have to break down lumps of material. Your earlier video highlighted this principal.

can of worms there Teemore layful: I am no physics expert and will just take Jack's word for it. Also looking forward to seeing a review.

Dihusky your logic is correct ' but my later designs would not suit having a built in classifier :beer:
