A ball mill is a type of grinder used to combine and grind materials into QDs or nano size using varioussized balls. A planetary ball mill is literally loaded with balls, which is why it is nicknamed a "ball mill."Ball mills like the laboratory ball mill or industrial ball mill work by utilizing the force of the moving balls. They don't require a cutting instrument as a result.
