Selection depends on mill type, feed size, impact conditions, ore abrasiveness, target output and current wear data.
Optimize ball size distribution, hardness, alloy grade and charging strategy according to real operating data.
Forged balls suit high-impact SAG and primary grinding. Cast balls suit medium-impact and cost-sensitive ball mill applications.
Yes, engineers can review mill data, wear patterns, operating conditions and recommend suitable media.
