Ball Mill Motor Failure Root Cause Investigation - CGK

After several years of running without electrical issues, the ball mill motors began failing. In less than a two-year span, four 5000 hp motors had failed. Each incident resulted in an average 100 hours of production downtime and significant repair costs, amounting to approximately $1,000,000 in losses per incident.
