In 2016, Sirona updated their mill lineup with dry milling technology to speed up the processing of zirconia. This was accomplished by adding a dust vent on each side of the milling chamber and a suction unit to remove and store the zirconia dust. According to Sirona, there is no difference in accuracy or quality between wet and dry milling.
Zirconia balls are most commonly used as check valves in flow control applications. When subject to stress by impact, grinding, or cracking, a zirconia ball undergoes "transformation toughening" which stops cracks from spreading and actually makes the ball stronger in the stressed area than what it was originally.

Absolute ethanol (Merck, Germany) is used as a solvent media for wet milling. For the homogeneous mixing of the powders 24 hours pot milling is continued by motor driven mill with yttria stabilized zirconia balls as a grinding media. Then the mixture was dried in a vacuum oven (UE600, Memmert, Germany) at 100˚C for 24 hours. ...
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
zirconia balls have following advantages in solid state synthesis in ball milling. High crushing strength and fracture durability, superior wear resistance which has no any break under high speed...

Ball Milling: Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.
