I've got a bit of some Acacia leaf and bark and would like to know the best way to get the leaves and bark grinded into a fine powder. This was on I've put the leaves through the mulcher I have

and it just shreds them a little bit as it spits them out.

The coffe grinder works okay but would take too long and probably break before I had enough.

How do you think fresh leaves would go in a food processor?

What does everyone use to get their leaves to powder or at least properly mulched?

Maybe I might try and run the leave over with the lawn mower.

I tried the lawn mower and didn't do much better than the mulcher. I've had to do it in the coffe grinder which took a while but still worked okay.

Still looking for some ideas since I don't think my coffe grinder will last if I keep using it for chewing up bark and leaves.

I have used the same cheap coffee grinder for three years--just the tiny kind with the lid with the button you have to push on top. I just pull apart my bark and twist it by hand, and make sure none of the pieces are too big to get stuck inside.
