Processing Aluminium Shavings

[Bju90]

I have access to Aluminium shavings from a machine shop. Is there a safe way to process these down? I don't need a fine powder but something like 40-60 Mesh?

I also have access to some Titanium shavings, although Ti mechanical properties I could imagine make this more challenging. 

Ti spone too but this is a bit expensive. This is much finer to start off with and should be quite brittle so I'd imagine I could manually process this without too much difficulty. 

Edit: I just found a few pieces of old bar stock offcuts too. I'd prefer not to but I could make some finer shavings using a file by hand or with a drill press and the right tool.
