At a mining operation in the United States, an overburden conveyor and stacker system operating 160,000 tons per day of 14" material was experiencing extensive wear to the conveyor transfer points. Originally lined with 3/4" thick 500 brinell carbon steel plate, the average wear life was approximately 3 days, and only 480,000 tons. The lack of wear life led to unscheduled shutdowns and increased total costs.
