Sand blaster issues
Ok I have a pressure type sand blaster. I have found that you need three things to keep it working.
1 dry sand, 2 dry air, and sifted sand.
I bought a few bags of Black Diamond 20-40 grit. When I went to screen/sift it I found that about half the sand would not go through the screen. I donít want to throw this away, so I thought that I could grind it some how. Has anyone run into this situation and if so any thoughts on how to grind it down to a usable grit?
