om...
I just got a small tumbler that I intend to use for de-burring small
aluminum parts.

Would that be a drum-style rotary tumbler or a bowl-style vibratory tumbler?


Does anyone have any advice on what media to use in it?

Depends on the type.


I was thinking of trying sandblasting sand...

Not very effective or efficient in either type of tumbler.


And any idea of about how long to run it?

Depends on the type of tumbler, the type of media, the size and shape of the
parts, and the degree of deburring needed. The only real way to know is by
trial and error. If doing a lot of similar parts, you can get an idea of the
amount of time required after judging one or two trial runs. But if each
batch is different in some way, then you will have to test every time.
