autogenous mills – commonly known as SAG mills – use milling balls, as well as the weight of the ore itself, to break down the ore into smaller particles – a process known as comminution. The turning and tumbling of tons of ore within these mills creates a harsh environment with high heat and constant vibration. Downtime for these
