    There is a limit of ball diameter below which centrifuging of mill charge occurs this limit can only be overcome by a change in the manner of ball movement In sandmills the grinding charge is driven by an impeller Sand used in such mills has a diameter ranging from 0 5 to 1 mm in beadmills glass beads have a diameter ranging from 1 to
