    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. Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills particularly when the large mills carry 40 by volume ball charges. This paper will explore factors used in scaling up ball mills showing where the advantages of one factor can possibly be negated by another factor.
