Secondary Grinding – Ball Mills In secondary ball milling, abrasive and corrosive conditions predominate. The smaller balls [< 2½”, (65 mm)] typically used in secondary millingenvironments effectively reduce the impact component of wear to the point where grinding media must be primarily designed to reduce abrasive and corrosive wear.

In 1991, twoautogenous grinding millswere installed replacing two stages of crushing, one stage of rod milling and one stage of primary ball milling. The cyclone overflow P80 of the secondary ball milling circuit was reduced to 120 microns due to the increased operating power in the AG/SAG mill circuits. ball mills in secondary milling
