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.

Criteria in Selecting Size of Zirconia Grinding Media · Larger-sized media are more efficient in breaking up large particles. · Smaller media are more efficient in milling smaller particles because of higher effective contact area. · Larger media sizes are favored in many conventional ball mills. Smaller sizes are more appropriate for attritors.

Khumalo et al., 2006 postulated that generally larger sized grinding media would break larger particles quicker but a finer product would be obtained by use of smaller balls. However, use of smaller grinding media is believed to support abrasion and attrition (Katubilwa et al., 2011) which are energy inefficient breakage mechanisms .
