In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.closed circuit ball ore mill btb-uwbewindvoerder.nl,Closed Circuit Ball Mill Grinding Mining Closed-circuit grinding is a size-reduction process in which the ground material is removed either by screening or by a classifier and the oversize is returned by integral classification to the mill Iron Ore Grinding Process Process Design For Grinding.
