Application of Grinding Media Steel Balls
CertificationsSAG Mill Use Effect
According to one of use reports of Φ9.75x4.88m SAG mill in copper mine, on the basis of completely meeting production conditions and technical requirements, our grinding ball consumption is
about 0.38kg / t , so it saved 1416.00 tons grinding balls a year which can finally save at least 10% purchase cost in grinding balls.Packaging & Shipping
