Ball Mill Principles Ball mills, sometimes referred to as pebble mills or tumbling mills, are milling machines that take the form of cylindrical vessels containing balls mounted on a metallic frame that can revolve around its longitudinal axis. Depending on the feed and mill size, balls with varying diameters occupy 30 - 50 % of the mill volume.

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 abrasive forces generated ...
