Media Blasting

[MikeA]

Sorry if this was asked before but what material do you guys use for media blasting? I am primarily cleaning rusted parts (aren't we all!!). http://www.yenko.net/ubbthreads/images/graemlins/smile.gif

I mostly use glass bead in my blast cabinet.

Recycled Glass............Fine but cant recall grit size

I start out with medium grit glass bead in my cabinet because it last a little longer than the fine grit. Mark

Thanks for the response.

Are glass beads good for heavy rust removal? I am using coal slag and it works great but I am concerned about breathing in the dust. Does anyone use coal slag (Black Blast) and should I be overly concerned about the dust?

Aluminum Oxide works good on rust and scale, comes in different grits.
It does upset the metal slightly.

Hey, it was dirty after all those miles on the HRPT. I just thought it needed a wash http://www.yenko.net/ubbthreads/images/graemlins/naughty.gif

plastic media does fine job at cleaning part without harming the finish, will remove light surface oxidation. Glass grit will do a nice job to remove RUST.

I will give the glass beads a try. I did try the aluminum oxide however it did not seem work real well due to moisture in the line.

Well moisture in the line will be a big problem. Buy a small water trap and place it before your blasting area. This could be one of your problems because water will slow down your process by clumping your media together. I have three traps before my blast cabinet and I have never had a problem. Good luck, Mark
