The Mill Vibration Anomaly Detection AI Agent brings insurance-grade risk monitoring to the plant floor by detecting the earliest signs of mechanical distress, preventing breakdowns, and enabling data-backed underwriting and claims outcomes.

What is Mill Vibration Anomaly Detection AI Agent in Cement & Building Materials Equipment Monitoring?

The Mill Vibration Anomaly Detection AI Agent is an AI-driven condition monitoring system that analyzes mill vibration signals to detect abnormal patterns indicating emerging faults in bearings, gearboxes, rollers, trunnions, liners, and drives. It provides early warnings, root-cause insights, and risk scores that inform maintenance, operations, and insurance decisions. In practical terms, it turns raw vibration data into actionable, insurance-ready intelligence for uptime, safety, and loss prevention.

1. A precise definition tailored to mills

The agent ingests accelerometer, velocity, and acoustic emission data from ball mills and vertical roller mills (VRMs), applies signal processing and machine learning, and flags deviations from normal operating states. It isolates fault signatures such as bearing defect frequencies (BPFO/BPFI), gearbox mesh frequencies, and misalignment or imbalance indicators, delivering evidence-backed alerts and recommended actions.

2. Insurance-grade monitoring

Unlike generic condition monitoring, the agent structures outputs—severity, confidence, time-to-failure estimate, and control recommendations—in line with equipment breakdown and property insurance needs. This makes its insights usable for underwriting credits, risk engineering, and claims substantiation.

3. Standards-aware

It aligns with ISO 20816/10816 vibration severity guidelines and ISO 17359 condition monitoring recommendations, enabling consistent thresholds, comparable benchmarks across plants, and audits.

4. Human-in-the-loop by design
