Maintenance Strategy - an overview ScienceDirect

Scheduled offline maintenance or failure of one of the Ball Mills (or its ancillary equipment) causes a 50% loss of milling production. Most of the maintenance results from time-dependent failure mechanisms (e.g. wear, corrosion or fouling). The crushing circuit has a mean running time to failure of 6 months.
