How about a hand cranked fan blade with a small pulley hooked up to giant pulley with a handle to turn it.
Lot of fan for one turn of handle. No leaf-blower noise or power required.

Definately worth experimenting with, I can see some potential with the concept, seperation may be an issue and will require a lot of thought initally prior to building anything. Good luck. Ken.
I am interested because apparently centrifugal force has an exponential effect on some thing according to its specific gravity. So if you spun it fast enough maybe you could dislodge all the other material by using a smaller but higher pressure blast of air. Screening of gravels could be done with grills at a slight angle rising from the center to the sides so the larger bits climb up and out over the sides, smalls continue flat until they are met at side wall with air blast that's also keeps the whole thing spinning.

best its realevant, 'snake' - hiss of the brushless..
unless your inventing a rolled shark tooth cell matting(blowing dirt out of a grey nurses mouth type thing)..
A lot of people have brushless drills these days. Could put a nut in the centre it could attach too.20xwater said:Goldfreak said:Hahaha, or gold tornado ! Oh I got it, gold Sharknado !20xwater said:

Now that's a better idea, few moving parts :Y:
If you had something like a 44 gal drum pivoted on the circle ends similar to the mulch bins you see at bunnings.
Then perhaps have the drum slightly bigger diameter at one end so the material naturally made it's way to that end.
That opening could then have a bigger catch rim, like a gutter that was bent all the way around the circumference, hopefully, that is where the gold would end up.

wtf is it ?

Well its got no motor atm but it would need some pressure to keep it going once its full of water and dirt!

Hehe its a gold centrifuge, what I was going to do is put it at the end of the launder, the material goes in, the thing is spinning at a certain revs and the lighter stuff gets thrown out the top and the gold goes to the bottom.
