Planetary Ball Mills 101
Planetary ball mills share the same design as other basic ball mills – a grinding jar filled with media and rotated on its own axis. But their unique design takes advantage of centrifugal force and the Coriolis effect to grind materials to a very fine or even micron size. These forces come into play as

Grinding ball data
The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.
