SAG Mill Liners for Mining Grinding Equipment
SAG mill liners are replaceable wear-resistant parts installed inside semi-autogenous grinding mills. They are designed to protect the mill shell from abrasion, impact and continuous contact with ore, grinding media and slurry during mineral processing operations.
In mining grinding systems, SAG mills work under demanding conditions. Large ore particles, grinding media and rotating motion create strong impact and wear inside the mill. Suitable SAG mill liners help protect the mill structure, improve grinding stability and support planned maintenance.
