Ten years ago I did a lot of looking at designs for cyclones,but never built one. But recently wanted to make a dust collecter for a sand blaster in the shop that I do little things for.

Anyway found that one can buy the cyclone bit on AliExpress or Ebay in a bunch of sizes. One suitable for use with a shop vac runs about $18. Took a long time to get here, but works well. Made of plastic so will not last forever, but still worth while.

Mind posting a link. I recently unplugged the heavy duty hose on my
shop vac and started using it to clean up the bulk of the chips in the
mills again. I'd love to have the most of them drop right into a trash
barrel. Maybe if most moisture dropped out there too I could put a
filter back in the vac.

Been thinking about making Thein seperator, but... well... time.

No problem. The one I bought was $ 18.01 from Magicalcarworldstore.

I got there by searching on " Ali " which should bring up AliExpress.com.

Then search on " clone filter " select " free shipping " and change the " search by " from " best match " to " price "

If anyone knows how to post a URL directly , please post it.

I always filter by "Orders" because often the lowest price is a store
that has not a single sale of this product, or has a visibly inferior
version that people don't choose, or some other reason to avoid them.

Always cut off the URL at the ? for AliExpress.

Here are a couple of links, slightly different products:

Found a few on Fleabay with "US STOCK" for a few dollars more and free
shipping. I went ahead and ordered two different ones to play with. If
I can use something like a 45 gallon Brute trash can or even a 55 gallon
barrel that would be great. If they don't work that well they still
didn't cost much.

You have probably already had a look on youtube but if not there are a bunch
of construction videos on how to put together a dust collector with various
shop vacs or bigger blowers, with homemade cyclones or the commercial ones.
If you want a small, portable unit you could adapt this one:
https://www.youtube.com/watch?v=C7KQ_p8IDAg, or the one he based his on:
https://www.youtube.com/watch?v=WyBuRjO54NM. They used 5 gallon buckets to
hold the dust/wood shavings, not 45 gallon, but I think they are pretty
clever and simple to build so you might get a useful idea or two.

A funny thing about cyclones is the separation efficiency is dependent
on the velocity of the fluid and the diameter. They don't scale.
Bigger isn't better. I was surprised as a young researcher in
Magnesium to see the Dorr hydroclones. We processed about 80,000 gpm
seawater with about 1200 ppm Mg, the mag hydrate was initially settled
in ponds with huge rakes, then the slurry was pumped from the center
of the ponds to the hydroclone house where hundreds of very small
cyclones were manifolded together. The further concentrated mag
hydrate came off the bottom, clears from the center. Each cyclone
wasn't over 2-3" in diameter. Mag hydrate is a very tiny particle, so
it took a lot of force to separate it from the seawater.

Of course aluminum chips in air are going to come out orders of
magnitude easier, so it probably won't be an issue at any size you can
use. You've handled a 45 gal can half full of Al swarf? Not too
heavy? Anyway, hope it works well.
