A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.
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.
Oct 18, 2017 Small-scale ball mill tests are convenient but could give misleading results because they do not produce the severe ball impacts of full-sized mills. During ball milling, balls are subjected to three conditions impact, abrasion, and corrosion. Much effort has been made to simulate these conditions in the laboratory. The impact of balls in mills is known to
