Can you grind other things besides meat in a meat grinder?

Question by Michelle:
Can you grind other things besides meat in a meat grinder?

we are looking for a heavy duty grinder for food. we need a grinder to grind up roots into powder, and we don’t think that a coffee grinder will do the job.
can we put things besides meat in a meat grinder?
if not, what would you suggest grinding roots in?
we are looking for an electric grinder.
thank you.
