Blasting cabinet

No, I've never seen them, just did a search and they are expensive.
I can see a lot of micro plastics being generated and disposal could be difficult if done properly.

I have read that there are (2) kinds.
1. made from thermoplast material (able to be remelted)
2. made from thermoset material like bakelite & melamine.

#2 is harder, and maybe reinforced with glass or other fibers.

I have read that the thermoplast kind (I'm thinking of ground up milk bottles)
you can blast a decal off a windshield, and not scratch the glass.

At work, we had a custom machine to blast clean the armature winding slots
during re-building. The material looked like Tide laundry soap, and was supposed
to be recycled many times.....if run at 50 psi.

Our guys cranked it all the way up to supply pressure (100 psi) for a "better job"
and it was a "once thru and to the dust collector" operation, shattered on impact.

They ended up going thru so much, they built a suction venturi to pull it from the drum, and
put it in the machine, as scooping was too hard.....

I need a venturi recycling tool to get the really fine dust out of the media.
I have used the 2 seive method before but it's really time consuming.
The fine dust does end up in the chip collector but only a very small percentage.

It would be great to get rid of the portion of the media that does nothing but cloud your view.
It's amazing the difference in the amount of dust generated when fresh medua is used.

A project for another day.

Yes. IIRC the automated blaster for the armatures ran something for this.

It had a dust collector spin separator device, the heavy went down the center, and dropped into the top
of the dual section pressure pot, and the dust went to the bag house.

Sort of tested the abrasive each time it went thru the blaster.
Here is a diagram of it:

Clemco has info on their "air abrasive washers" used on jobsites to reclaim.
IIRC it had tilted vibrating screens, and then a magnet, and a blower to take out the fines.
I think a small one could be made into a 12" square plywood column approx 6' tall.
