To produce particles smaller than 1 micron typically necessitates the use of a specialized type of bead milling equipment, referred to as a nano bead mill. The primary distinction between this equipment and a traditional bench style milling machine is in its respective pumping mechanism and grinding medium dimensions. For example, nano bead mills regularly employ very tiny media  as small as 0.05mm and as big as 0.30mm. Since the media are very fine, it is essential to equip the machine with a very precise separation mechanism to separate the media from the finished product. Examples of applications for nano bead mills include the manufacture of inkjet printer ink for the printing industry, manufacturing battery ceramics for electronic devices, and creating pharmaceutical nano suspensions.
