Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls). Rotary Mills: Small cylpebs (<1") are effective in ultra-fine wet regrinding operations. SAG Mills: 4"-6" forged-steel balls are recommended. Cast balls are not agood choice.
