  • Increase throughput and capacity in SAG mills

    A gold-processing plant I visited recently valued their SAG mill downtime at US 130 000 per hour so extending the life and availability of mill liners is crucial to them. The reduced damage improves the mills availability and minimises the downtime. This can translate to literally millions more tonnes of ore milled.
