Ball mills are the most common and versatile type of grinding
mills. They are remarkable in that they can operate over a very wide
range of conditions and geometries. Ball mills may be used for
primary, secondary, tertiary and regrind applications. In a mineral
processing plant, they are often used for a secondary grinding duty,
which directly links with downstream recovery processes such as
flotation [21,22]. Mild steel or stainless steel balls are generally used
as grinding media in ball mills for processing of sulphide ores to
achieve the required liberation size. Grinding circuit operators have
long been aware of the significant impact of grinding media consumption
on the cost of grinding. It is estimated that comminution
includes 30e50% of typical mining operating costs, and of these,
liner wear and media consumption account for roughly 50% of the
cost [1,19]. Therefore consumption of grinding media forms a significant
part of the operating cost in mineral processing industry.
According to Ref. [11] grinding medium wear can constitute up to
40e45% of the total operation cost in comminution process.
