Early bearing damaged detection on a large centrifuge

Subtle anomalies flagged bearing damage before it escalated.

Executive summary

The AI detected a bearing fault long before traditional alarms would have triggered. This gave us the opportunity to plan the replacement on our terms, avoid unexpected stoppages, and protect such a critical part of our process.

A starch producer improved the reliability of its critical drying process by equipping a large centrifuge with triaxial wireless vibration sensors connected to Viking Analytics’ AI platform. Traditionally dependent on monthly route-based inspections, the team now benefits from continuous anomaly detection and prioritization insights. The system flagged a bearing defect in the centrifuge basket side, even before vibration levels increased. With this early warning, the maintenance team could plan the 36-hour bearing replacement proactively, preventing extended downtime and costly production losses.

Triaxial wireless sensor with Viking Analytics machine learning algorithms

  • Challenge

The centrifuge is a critical part of the starch drying process. With only monthly inspections, failures could develop unnoticed, leading to sudden breakdowns. Replacing the main bearing is a labor-intensive 36-hour task that must be carefully scheduled. Without early detection, a failure could result in weeks of downtime before production could resume.
