Gardening Methods

what machine/tool/process could best achieve this job?

i want to ground up a dozen bags full of various chinese herbs and plant matter into a fairly fine powder. Obviously I don’t want to take all week doing it in a cuisinart or small blender. I’ve looked into leaf shredders but think it might not be fine enough. Though I don’t want to spend a thousand dollars on something. Ideal would be some addaptation I couldmake to a power tool or some common gardening tool, something I could rent.

Use a restuarant sized kitchen liquidiser.
