Digital Twin.

The digital twin is the foundation everything else stands on. It is a continuously calibrated, first-principles model of your full circuit — mass balance, mill filling, power draw, breakage, classification — that re-anchors itself to live measurements every cycle. The MPC trusts the twin's predictions because the twin tracks reality.

In process control terminology, the digital twin is the process model — the mathematical representation of how your circuit responds to changes in feed rate, water addition, ball charge, and ore hardness. A process model that drifts from reality produces bad predictions; one that re-anchors every cycle produces reliable ones.

What the twin holds

• Mass balance — closed across every node in the SABC circuit, every cycle
• Soft sensors — mill filling, slurry density, and product P80 inferred between lab assays
• Power draw model — calibrated against measured motor power, not generic curves
• Breakage / classification — ore-specific parameters that update as the geology drifts

What you do with it

• What-if simulation — test setpoints, ore blends, ball charge, and circuit changes before touching the plant
• Operator training — the twin runs as a high-fidelity sim that mirrors the real circuit dynamics
• Early warning — overload risk, grind-out, and recycle build-up flagged minutes before they happen
• Audit trail — every controller move comes with a model-predicted outcome you can review after the fact

How it stays honest

Smart-instrument signals re-anchor the twin every cycle. The Rock Analyzer keeps the breakage model on the real feed. Mill load, motor power, and bearing pressure correct the filling model. Lab assays correct the classification model when they arrive. The twin is never allowed to drift more than a few percent from reality before it is pulled back.
