Every bucket tooth, shovel lip and crusher liner on your site is being consumed right now, hour by hour, and in most operations nobody can tell you the actual wear rate until something fails. Mining GET wear is one of the few maintenance costs that is completely predictable in principle yet almost never measured in practice, so teeth get changed when they look bad, liners get changed when throughput drops, and adapters and bucket lips get destroyed quietly behind them. The result is a wear parts budget that feels like weather: it just happens to you. It does not have to. With a simple measurement routine, clear replacement thresholds and a record of what each product actually cost per hour, wear parts become a managed cost instead of a surprise. This page walks through how to build that routine, what thresholds to hold, how to stop a lost tooth from wrecking a crusher, and how to prove which product earns its place on your machines. If you want to see this running on your own fleet rather than reading about it, you can book a 30-minute walkthrough of wear parts tracking in HVI and bring your own numbers.
What does one bucket tooth actually cost you per hour? If you cannot answer, the tooth is not the problem.
Teeth, lips, adapters and liners are consumed continuously and measured rarely. Track wear rate, replace on threshold, and stop letting a $40 part destroy a $4,000 structure behind it.
Wear parts tracking in mining: four numbers that decide your budget
Most sites know their fuel burn to the litre and their tyre hours to the unit, but cannot say what last quarter's teeth, lips and liners cost per operating hour. These are the four figures that change that conversation.
Of total operating cost
GET and wear liners typically sit in this band on loading and crushing fleets. On a $12M annual site budget that is $360,000 to $600,000 you either manage or absorb.
Life difference between products
Two tooth systems in the same material can differ by double in service hours. Without measured wear rates you are picking by price tag and habit, not performance.
One tooth in a crusher
A detached tooth through a crusher means cracked mantles, damaged concaves, days down and an emergency liner change. The tooth itself cost less than a tank of fuel.
Typical GET overspend
Sites that move from reactive change-outs to threshold-based replacement routinely cut wear spend by a fifth or more, simply by stopping early changes and late disasters.
How a worn tooth becomes a rebuilt bucket
Ground engaging tools are a sacrificial system. Each layer exists to wear out so the layer behind it does not. When you run one stage past its threshold, the wear does not stop - it just moves somewhere far more expensive.
Tooth point wears
The point is designed to be consumed. Penetration drops as it dulls, fuel burn climbs, cycle times stretch. Cost to fix: one point, minutes, pocket change.
$ - replace on scheduleAdapter nose exposed
Run the point too short and the adapter nose starts taking the abrasion. Adapters are welded or locked on and cost many times the point. Now every hour of delay has a multiplier.
$$ - replace immediatelyLip and bucket structure
Once adapters wear through, the lip itself goes. Now you are cutting out and re-welding lip sections, or buying a bucket. A $40 decision became a $4,000 to $40,000 one.
$$$$ - unplanned rebuildThe same chain runs inside your crushers and mills: worn liners stop protecting the shell, and a liner change that could have been planned into a shutdown becomes an emergency with a crane, a crew and a silent plant. If you want help setting thresholds that hold, walk through a threshold setup on a demo call with your own machine list in front of you.
Bucket teeth and liner wear: measure it or lose it
You cannot manage a wear rate you never measure. The routine that works on real sites is boringly simple: same points, same interval, same tool, recorded against the machine - not a notebook that walks off with the night shift.
| Component | What to measure | Typical interval | Replace at | If you miss it |
|---|---|---|---|---|
| Bucket teeth / points | Length remaining, profile vs gauge | Weekly or every 50 hrs | Before adapter nose is exposed | Adapter wear begins, 5-10x cost |
| Adapters | Nose wear, fit and retainer condition | At every tooth change | At OEM wear limit, never past | Lip damage, weld repair, downtime |
| Shovel / bucket lips | Ultrasonic thickness at marked points | Monthly or every 500 hrs | At minimum thickness spec | Lip failure, bucket rebuild |
| Crusher liners | Profile measurement, remaining thickness | Per shutdown or per OEM plan | At wear limit, planned into shutdown | Shell exposure, emergency change-out |
| Chute & hopper liners | Thickness grid, visual + UT | Quarterly or by tonnes | Before substrate shows | Holed chute, spillage, structural repair |
The pattern that separates managed sites from reactive ones is not the tools - it is that every reading lands in one place, against the asset, with a history you can trend. That is exactly how HVI treats wear components: as tracked assets with their own measurement history, not as line items on an invoice. You can start logging wear readings free and have your first trend line inside a month.
Tooth loss detection: the cheapest insurance on your site
A missing tooth is not a parts problem, it is a plant-stopping event waiting for a crusher to find it. Metal detectors and belt magnets catch some; the rest get through. The only reliable control is catching the loss at the face, before the bucket dumps.
Without a check routine
- Tooth shears or unseats mid-shift, nobody notices
- Next bucket dumps it into the haul truck or feeder
- It reaches the crusher: cracked mantle, scored concaves
- Days of downtime, emergency liner change, six figures gone
- No record of when it was last seen intact
With a logged GET check
- Operator photographs the bucket at shift start and end
- Missing tooth flagged in minutes, dig face searched
- Tooth recovered or loads diverted before the crusher
- Timestamped photo record proves the check happened
- Loss history shows which machines and locks keep failing
This is a two-minute addition to a pre-start inspection, and it is the single highest-leverage check in mining GET wear management. HVI's digital inspections make it a required photo step with instant defect-to-work-order, so a missing tooth cannot be ticked past. If your crews still report this stuff by radio and group chat, see the defect-to-work-order flow in a live demo.

GET selection and cost per tonne: the honest comparison
The cheapest tooth is the one with the lowest cost per operating hour in your material - not the one with the lowest price. A premium point that lasts twice as long in abrasive shot rock wins even at double the price. A premium point in soft overburden is money burned. You can only tell the difference with data.
(Part price + change-out labour + downtime cost) / service hours = true cost per hour
Worked example: Tooth A costs $85 and lasts 220 hours = $0.39/hr. Tooth B costs $140 and lasts 500 hours = $0.28/hr. Tooth B is 65% more expensive and 28% cheaper. Multiply that across 12 machines and 4 changes a year each and the "expensive" tooth saves you roughly $5,300 annually on points alone - before you count the labour hours and machine downtime you did not spend changing them.
Match the product to the material
Abrasion-resistant alloys for shot rock and quartz-rich material; tougher, impact-rated systems for ripping and mixed ground; penetration profiles for hard digging. The right answer changes pit to pit, sometimes bench to bench.
Trial it properly
Run the new product on one machine, same operator, same material, and record install date, removal date, hours and condition. Without that record, every trial ends in an argument about feelings.
Plan liner changes into shutdowns
Trend your crusher liner wear rate and the change-out date predicts itself. Order parts ahead, book the crew and crane into a scheduled shutdown, and never pay emergency rates for a job you saw coming for months.
Watch consumption, not just stock
Parts and inventory data should tell you teeth used per machine per month, not just what is on the shelf. A sudden jump in consumption is a worn adapter, a changed material or an operator problem - all worth catching early.
Wear package management, built into the same system as your inspections and work orders
Wear parts as tracked assets
Every tooth set, lip and liner gets its own history: install date, hours, measurements, removal reason. Trend wear rate per machine and per product, and thresholds trigger the replacement work order automatically.
Parts & inventory that show consumption
HVI's Parts and Inventory records every issue against the machine it went on, across multiple shops and laydown areas. You see consumption per asset per month and cost, not just a stock count.
Expense Track & cost per machine
Expense Track and Cost Analysis roll every wear part, labour hour and downtime event up to the machine, so cost per operating hour is a report you pull - not a spreadsheet you build at quarter end.
Photo-backed GET checks
Bucket photos become a required step in the pre-start DVIR on any phone, with timestamped, audit-ready records. A missing tooth converts to a work order in seconds, not a radio call nobody logged.
It runs on any phone or tablet at the face, in the shop or at the crusher, alongside your trucks, trailers and the rest of your mixed fleet. Book a demo and we will load one of your machines live so you can judge it on your own numbers.
Mining GET wear, managed in five moves
Measure on a fixed routine. Same points, same interval, recorded against the machine. A wear rate you cannot see is a budget you cannot defend.
Replace on threshold, not appearance. Teeth before the adapter nose shows, liners at spec thickness. Late replacement transfers destruction to structures that cost 10 to 100 times more.
Treat tooth loss as a plant-stopping hazard. A logged photo check at shift start and end is the cheapest crusher insurance you will ever buy.
Compare products on cost per hour. Price tags lie; service hours in your material do not. Trial properly and keep the record.
Plan liner changes into shutdowns. A trended wear rate turns emergency change-outs into scheduled work with parts, crew and crane already booked.
None of this needs new hardware or a reliability department. It needs one place where readings, photos, consumption and cost live together. That is the whole idea behind HVI, and you can sign up free and set up your first wear package today.
"My gripe was never the cost of teeth - it was that nobody could tell me why one loader ate twice as many as its twin. Once we logged every change with hours against the machine, the answer fell out in six weeks: worn adapters on one unit and an operator who liked to ride the bucket. We track cost per hour on every GET product now, and I will not approve a brand switch without trial data. It ended the arguments with the supplier rep, too - I just show him the trend line."

Mining GET and wear parts tracking: your questions answered
How often should bucket teeth be inspected on a mining fleet?
Visually at every shift start as part of the pre-start inspection, and measured at least weekly or every 50 operating hours. The daily look catches tooth loss and sheared locks before they reach the crusher; the measured check tracks wear rate so you replace on threshold instead of appearance. High-abrasion material may justify a tighter interval.
What is the real risk of a lost bucket tooth?
A detached tooth that reaches the crusher can crack mantles, damage concaves and force an emergency liner change - routinely a multi-day, six-figure event once you count downtime, crane hire and parts. Detectors and magnets help but miss plenty. The reliable control is a logged bucket photo at shift start and end so a missing tooth is caught at the face, not in the crusher.
How do I compare two GET products fairly?
On cost per operating hour, never on purchase price. Run each product on the same machine, same operator and same material; record install and removal dates, hours and condition; then divide total cost (part plus labour plus downtime) by service hours. A product that costs 65% more but lasts twice as long is the cheaper option. HVI's Expense Track and Cost Analysis produce this comparison from your own records - book a demo to see the report on real data.
When should crusher liners be changed out?
At the OEM wear limit, planned into a scheduled shutdown - not when throughput drops or the liner fails. Measure the profile at each shutdown, trend the wear rate against tonnes crushed, and the next change-out date predicts itself months ahead. That lets you order liners, book the crew and crane, and avoid emergency rates for a job you saw coming.
Can software actually track wear parts, or is that a spreadsheet job?
Software does it properly because wear parts need the same discipline as any asset: history, thresholds, work orders and cost roll-up. In HVI each tooth set, lip and liner is tracked with its own measurements and hours, Parts and Inventory records consumption per machine, and Cost Analysis gives you cost per hour automatically. You can sign up free and retire the spreadsheet this week.
Stop letting $40 parts make $40,000 decisions
Put every tooth, lip and liner on a measured wear rate with thresholds that trigger the work order, consumption tracked per machine, and cost per hour you can defend in any budget meeting. See it on your own fleet in 30 minutes.
