Best Way to make uniform crushed glass at home Answered

I obtained an abrasive blaster and I decided to use crushed glass as the media. I have a steady supply of beer an wine bottles that I can crush but have a slight problem.

I am currently useing a capped steel pipe and a baseball bat to crush the glass. The results are anywhere from large quarter sized chunks to dust.

I want to have crushed glass roughly uniform in size as well as to be able to make larger or smaller sizes depending on the application (rust, paint, etching, etc).

Does anyone know of a way a DIYer could make a uniform crushed glass abrasive to use in a blaster?


Ball mill?

I thought of that but wanted to know of a way to make larger pieces. Ball mills tend to make more powder then actual crushed glass. On top of that I would have to rig in a way to screen as it went otherwise 1/2 would be powder.

So, you're after "splinters" then?

Maybe make a ball mill type device, with small holes drilled - as soon as the glass gets to the size you like, it will fall out of the holes before being made into powder. Hopefully.

It's not the trousers, it's what in them...

Well done, sir, well done! A double-reference double-entendre in a single thread.

And you know, between the drivel, I think I helped drakesword.

I will attempt this tomorrow. I have a broken self propelled mowing deck I will cut in half and use as the driver.
