I've worked on big stationary versions of this. They'll generally have four or five grades from oversized rejects down to flour. No finesse or elegance. Just big dumb machines that'll rattle the fillings out of your teeth.

I once spent five months with another worker picking human bones (and fragments) off a sifter like that. Only 2 grades, though: 'chunky' and 'smooth'.
