Ball and Pebble Mills: The expressions "ball milling" and "pebble milling" are frequently used interchangeably. Usually, however, a ball mill is referred to as one that uses steel balls as grinding media, while a pebble mill is one that uses flint pebbles or manufactured ceramic shapes. Fundamentally, milling is a process for reducing ...

The media media most used in all milling applications are made of zirconia. But if the purpose of ballmilling is to blend materials softer than zirconia, alumina media is recommended to avoid breaking the dispersed powder. Using grinding balls with different diameters, 3 or more, improves the particles dispersion in the ceramic slurries.
