Reliable fault detection on a SAG Mill with on-line vibration monitoring system

Dana Lake, OneProd and Service Manager , ACOEM


This paper will show the advantage of an on-line continuous vibration monitoring compared with the regular surveys using portable equipment. It will present two case studies of detecting bearing faults in a Semi Autogenous (SAG) Mill on a mining side; one in a gearbox, the other one in the motor. Both faults have developed rapidly and would have been missed by the, already in place, 6-weekly vibration surveys.
