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.
A ball mill is a device that uses balls, or similar media of heavy material that fall onto and crush the material being milled. The falling and crushing process is confined within a jar and the crushing action is repeated thousands of times to reduce the particle size of the chemical being milled.
