RME · What Is Mill Relining? Why Is It Important?
Almost invariably the AG, SAG and Ball mill liner lives dictate the shut-down dates of the concentrator. The replacement of the mill liners determines the length of each concentrator shut-down. In other words, the liner lives and their replacement, define the time available for mineral processing.
