wet blaster ?
I made a 6 ft blast cabinet then my son bought a used 3 ft cabinet. On the big cabinet I made a 2 in plastic pipe into an exhaust, I drilled some holes along it and have about 20 ft of flex pipe hooked to a vacuum. and it is outside under a cover. I bought a wet blaster from northern tool, It hooks up to my 3500 psi pressure washer. I haven't done any large pieces, but NO DUST just a wet mess everywhere. I was digging a pipeline trench down by the river and found lava sand, clean enough to use for brick motor, an unlimited supply
