Sandblasting talk
i have a ton of real world experience and info on blasting but so many back yard experts who "read it on the internet" loudmouth any real useful info so i don't bother sharing much. this is my living so i take it seriously.
i have a three cabinets and about the dust. Here is the easiest way to control dust. i just replaced my $500 dust extractor on this new cabinet with a "dust deputy" (this is a chinese knock off from amazon) 6hp vacuum is below it. the dust deputy will pull 99% of dust out of the line before it hits the vac. it takes me about 30hrs to fill a 5gal bucket (bucket is below the deputy) and the vacuum has maybe 1/2 cup of glass bead dust in it. but.....the super fines will get on the vac filter so it needs to be checked every 15-20hrs. it works amazingly well. way better than a commercial dust vac set up. The vacuum line needs to be baffled as a straight line into the cabinet will pull too much media out. There also needs to be a air inlet on the other side of the cabinet. (left-right works better than both the inlet and outlet on the back wall) The air pressure can be controlled by adding a "sawdust gate" on the inlet (sliding trap door to open or close depending on how much pressure is needed to pull the dust) this set up is way less than a conventional dust set up and works 10x better.
