Ball Mill Working Principle. The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and ...
