Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).

The efficiency of ore enrichment and grind-ing largely depends on the quality of the grinding balls. In ore preparation for enrichment, grinding is the most expensive operation: it accounts for as much as 65% of the total costs [1]. More than 95% of the steel grinding components in mills are balls. Grinding balls are subject to repeated impacts ...
