The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
