A mid-sized cement manufacturer operating a single integrated plant in the U.S. South was losing an estimated $2.9 million annually to unplanned kiln shutdowns and rotating equipment failures. Cement kilns — the thermal core of every clinker production line — are among the most maintenance-intensive assets in heavy industry. At this facility, reactive maintenance consumed 61% of all work orders, vibration anomalies on critical rotating equipment were discovered only after failure, and no structured digital maintenance process existed for the kiln drive, preheater fan train, or raw mill circuits. Within eight months of deploying Oxmaint's AI-powered predictive maintenance and CMMS platform across the plant's critical asset base, the manufacturer reduced unplanned kiln downtime by 52%, cut mean time to repair by 38%, and moved from majority-reactive to majority-planned maintenance operations.

Reactive Kiln Maintenance Was Costing More Than the Equipment Was Worth to Run
The facility ran a two-kiln line with a combined clinker capacity of 3,400 TPD. Asset criticality was understood intuitively by senior technicians but had never been formally documented, and no CMMS governed work order flow or parts consumption tracking. Preventive maintenance schedules existed on paper but compliance was unverifiable. When rotating equipment faults surfaced — bearing failures on the kiln thrust roller, imbalance on the preheater ID fan, or gearbox wear on the raw mill — the team responded without diagnostic history, without staged parts, and without structured repair procedures. Capital budget requests went unsupported because no failure history existed to justify replacement timelines.
