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. ... The selection …

Because of this, you generally won't find a metal grinding mechanism in a salt mill. The preferred material for a salt mill grinder is ceramic, although you will also see plastic grinding mechanisms, particularly on cheaper models. Pepper, on the other hand, is a lot friendlier than salt and doesn't adversely affect metal components.
