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. ball mill closed circuit with hydro cyclones .
