Mill & Chute Liner Wear Tracker
Log liner thickness at reference point readings, see the wear trend and get a projected date when the 25 mm limit will be reached.
Readings stay in your browser (localStorage) โ nothing is uploaded.
Straight-line (least-squares) extrapolation of your logged readings to the 25 mm alarm threshold (warning at 35 mm). A low Rยฒ means the trend is noisy โ log more readings before trusting the projection.
Field notes from maintenance practice
Measure at paint-marked reference points during scheduled inspections โ ultrasonic from outside where geometry allows, depth gauge from inside otherwise. The real money is in matching the projection to planned shutdowns: relining a week early costs liner value; overrunning costs throughput (worn lifters stop lifting the charge) and risks shell damage, which costs everything. The default action limit of 25 mm comes from typical practice of replacing mill shell liners at 20โ30 mm remaining (or when lifter bars round off and grind efficiency collapses) โ set the liner supplier's discard thickness for your profile; adjust it if your OEM or procedure specifies otherwise.
Linear extrapolation is honest only when the Rยฒ is decent (โฅ 0.7) and degradation is steady. Liner wear rate shifts with ore hardness and ball charge, so refresh the fit with the latest campaign's points โ last quarter's slope predicts better than the lifetime average. If the last reading jumps far off the line, re-measure before believing it โ measurement technique drifts too.

About Mill & Chute Liner Wear Tracker
This tracker is a remaining-useful-life (RUL) estimator for liner thickness at reference point. Log a dated reading whenever you measure; the tool fits a least-squares straight line through your history and projects when it will cross the 25 mm action limit (warning at 35 mm) โ turning scattered measurements into a forecast date you can plan parts and downtime around.
How to use Mill & Chute Liner Wear Tracker
- 1Enter each dated measurement as you take it โ readings persist in your browser between visits.
- 2Adjust the alarm (and warning) threshold to your OEM or procedure limit if it differs from the default.
- 3Read the fitted trend, Rยฒ, days-to-alarm and the projected date โ then plan parts and downtime around that date.

Frequently asked questions
What limit should trigger action for liner thickness at reference point?+
The widely used limit is 25 mm (typical practice of replacing mill shell liners at 20โ30 mm remaining (or when lifter bars round off and grind efficiency collapses) โ set the liner supplier's discard thickness for your profile). Set a warning at 35 mm so parts and labour are ready before the alarm. Your OEM manual or internal procedure overrides the generic figure.
Grinding performance dropped before liners reached discard thickness โ why?+
Profile beats thickness: lifter bars that round off stop throwing the charge into a cataracting trajectory long before the plate liners are thin, so impact grinding dies while 'thickness' still looks fine. Track lifter face angle or height separately from plate thickness, and consider high-low or curved profiles that maintain trajectory deeper into the wear life โ suppliers will simulate this for your mill speed.
How many readings before the projection is trustworthy?+
At least 4โ6 spread over a meaningful fraction of the asset's life, with a fit Rยฒ of about 0.7 or better. Two points always make a perfect line โ that is curve fitting, not condition monitoring. Keep measurement conditions (load, temperature, location) consistent.
Is straight-line extrapolation valid for wear?+
It is the standard first approximation for steady-state degradation, and it is deliberately conservative to act on. Many failure modes accelerate near the end (bathtub curve), so treat the projected date as the latest acceptable intervention date, not a promise.
Where is my logged data stored?+
Entirely in your browser's localStorage on this device โ nothing is uploaded to any server. Export or note critical values elsewhere if you need a permanent maintenance record shared across a team.
