PLANT RELIABILITY.

Equipment Faults + Process Anomalies

Star Cement — a leading Asian OPC & PPC cement manufacturer — didn’t just digitize its plants. It closed the loop: from raw sensor signal to prescribed action to user-validated production outcome. And in under 6 months, it delivered 10X ROI.

What's inside

FROM NOISE
TO OUTCOMES.

Mechanical Faults
Vibration, wear & bearing degradation

Physics + AI models detect bearing defects, roller lubrication failure, and mill tripping conditions across Raw Mills, Coal Mills, and Kiln roller assemblies before they cascade into unplanned downtime.

Electrical Faults
Drive anomalies & energy drift

Continuous monitoring across PLCs, DCS, and Energy Meters at Line 1, Line 2, Line 3, CPP, and WHRS surfaces load imbalances and drive anomalies before they impact Captive Power Plant or Waste Heat Recovery output.

Process Induced Faults
Parameter drift & SHC deviation

24×7 monitoring across Crusher, Raw Material Handling, Clinkerization, Cooler, and Grinding sections detects process shifts — like moisture overshoot in CFA or kiln roller temperature rise — before they hit Specific Heat Consumption or throughput.

01

6 areas. 492 KPIs. One Single Source of Truth.

How Star Cement unified 4 plants — from the Meghalaya Integrated Unit to the Guwahati Grinding Unit — across Mines, Crushers, Raw Mills, Kilns, Coolers, CPP, and WHRS into a single contextualized source of truth. Logbooks, SAP, DCS, PLCs, Energy Meters, and Quality Systems — all ingested.

Physics + AI: precision that predictions can't match

PlantOS™ doesn't flag anomalies. It traces root cause — across mechanical, electrical, and process domains — with 99.97% accuracy. Zero missed faults across 492 KPIs spanning Line Material Handling to Clinkerization.

03

Diagnostic → Recommendation → Action

18 prescriptions executed at 99% acted-upon rate. Specific Diagnostic Reports — not vague alerts — moved Star Cement from "what is wrong?" to "fix this now." Roller bearing lubrication replaced. CFA moisture controlled. Work orders that close.

Outcomes the plant's own operators signed off on

46 hours of unplanned downtime prevented. 10 TPH throughput uplift. 920,000 kCal SHC saved. 600 tons of clinker production preserved. 5% MTBF increase. ₹47.8 Mn annual savings. All validated by Star Cement's own Reliability & Operations teams.

Validated outcomes

Prediction
≠
Outcomes.

Most AI deployments stop at the alert. They predict. They visualize. They dashboard. But prediction without a closed loop is just a more expensive alarm bell.

Star Cement’s deployment with PlantOS™ proves the gap isn’t in the model — it’s in the mile between insight and action. The 99% Trust Loop™ is what bridges it. And at Star Cement’s scale — 4 plants, 19 integrated systems, 492 KPIs — the results don’t just compound. The pay back was 10X in under 6 months.

The biggest change was the immediate establishment of a single source of truth. We moved from reactive chaos to proactive control.
