A cement plant's conveyor system never stops moving, which means it never stops wearing either. A misaligned idler, a belt tracking off center by a few millimeters, a splice starting to fray — none of it looks urgent until the belt tears mid-shift and the whole material flow stops with it. This case study looks at how a cement plant used predictive maintenance inside its CMMS to catch conveyor issues before they became line stoppages, and what happened to belt failures, idler life, and unplanned downtime. Sign up to see the same conveyor maintenance workflow built for your own plant.
The Challenge
Conveyor belts and idlers were walked and inspected on a fixed weekly round, regardless of how a specific section was actually wearing. Misalignment, bearing heat, and belt tracking drift went unnoticed between rounds, so by the time a tear or a seized idler was found, it was usually mid-run, and material handling stopped until someone could get to it.
Results After Monitoring Conveyor Condition Continuously
-45% Failures
Fewer belt failures once tracking, tension, and idler condition were monitored between inspection rounds
+34% Idler Life
Longer average idler life after bearing heat and seized rollers were flagged before failure
-58% Downtime
Reduction in unplanned conveyor downtime across the material handling line
Unplanned Downtime Hours: Before vs After
Average unplanned conveyor downtime per month, before and after belt tracking, tension, and idler condition were tracked continuously instead of checked only on the weekly round.
Conveyor Maintenance Before And After
| Area |
Before |
After |
| Belt tracking checks |
Walked and checked once a week regardless of belt condition |
Tracking drift and tension monitored continuously between rounds |
| Idler bearing condition |
Found seized or overheating only after noise or a stoppage |
Bearing heat trends flagged as a work order before seizing |
| Response to a tear or jam |
Reactive, line stopped until someone reached the fault |
Rare, since drifting sections are corrected before failure |
| Unplanned downtime |
Averaged 38 hours per month across the line |
Down to 16 hours per month across the line |
Stop Losing Production Hours To Belt Tears And Seized Idlers
Oxmaint tracks belt tracking, tension, and idler bearing condition continuously, so conveyor issues get fixed on a schedule instead of stopping the line. Sign up for a free trial to build your own conveyor maintenance workflow, or book a demo to walk through this case study in detail.
Conveyor Stoppage Events: A 30-Day Snapshot
Before condition monitoring
After condition monitoring
Each square represents one day. Highlighted squares mark days with an unplanned conveyor stoppage. Tracking belt tension and idler bearing heat between rounds turned a near-daily risk into a rare exception.
The Results
Material handling stopped being the weak link in the schedule. Belt tracking, tension, and idler condition were visible between inspection rounds instead of only during them, so a drifting section showed up as a work order days before it would have shown up as a torn belt. The team spent far less time firefighting jams and far more time keeping the line moving.
Frequently Asked Questions
Q
Why do conveyor failures usually happen between inspection rounds?
Belt tracking and idler wear drift gradually, and most plants only walk the conveyor line on a fixed weekly schedule, so a section that started drifting right after an inspection has days to worsen before anyone checks it again.
Q
What data actually predicts a belt tear or a seized idler?
Belt tracking drift, tension trends, and idler bearing temperature all shift before a tear or a seizure happens, so tracking those against historical baselines gives enough lead time to schedule a fix during a planned window instead of a forced stop.
Q
Does this help beyond avoiding tears, like idler replacement cost?
Yes, catching an overheating bearing early usually means swapping one idler on a planned basis instead of a seized roller damaging the belt itself, which is a far more expensive repair and a longer stoppage.
Keep Your Conveyor Line Moving, Not Guessing
Oxmaint tracks belt tracking, tension, and idler bearing condition continuously, turning early conveyor wear into a work order instead of a line stop. Sign up for a free trial to build your own conveyor maintenance workflow, or book a demo to walk through the full case study.
