New, rebuilt or used crusher: the real math

The used market is full of crushers at a third of the price of new. Some are excellent deals. Others end up, two years in, costing more than new — in unobtainable parts, downtime, compliance work and tonnes not produced. The difference between the two does not show on the listing; it shows in a calculation few buyers carry through to the end.

This article lays out that calculation, defines what "rebuilt" means when the word is honest, and gives the questions that separate the three options for a given case.

Three options, three different things

New. A crusher straight from the factory, with the manufacturer's warranty, complete documentation, parts in the catalogue for years, and — the weak point — a manufacturing lead time measured in months, sometimes more for large sizes.

Rebuilt. A used crusher whose critical components have been inspected, measured, replaced or reconditioned by the manufacturer or a qualified shop, with a report stating what was done and a limited warranty on that work. The value of the option rests entirely on the quality of that report: without it, "rebuilt" is just a word on a listing.

Used "as is." A crusher sold in its current condition, available immediately, with no warranty and a history that is sometimes complete, sometimes non-existent. The price reflects the uncertainty — and that uncertainty is the buyer's to carry.

The real math: total cost over the period of use

The purchase price is one item. The complete calculation lines up, over the planned period of use, everything the option costs and returns:

The item that tips the decision is rarely price: it is lead time when a shutdown window or a tonnage contract is at stake, and availability when the crusher is the site bottleneck. A machine that arrives three months earlier and produces at 90% can be worth more than a perfect machine delivered after the window. Conversely, on a remote site where every stoppage costs tonnes and a mobilization, the reliability of new is paid once and repaid at every stoppage avoided — what a blockage costs gives an idea of the order of magnitude at stake.

What "documented condition" means

For a rebuilt or used crusher, the file matters more than the photo. What it must contain:

1. The inspection report on major components: main shaft, eccentric, bearings or bushings, frame and shell (crack detection), wear parts in place, hydraulic system, lubrication. With measurements, not just "OK" ticks.
2. The history: operating hours, rock processed, major interventions, replacements — even partial, it says a lot.
3. The model's status with the manufacturer: still supported with parts available, or discontinued with parts to be custom-made.
4. The drawings: overall dimensions, anchor points, interface dimensions — essential to check that the machine fits your layout.
5. Compliance: guards, emergency stops, motor and electrical equipment compatible with the site's and the jurisdiction's requirements.
6. Provenance: proof of ownership and absence of liens, especially for a machine coming out of a liquidation.

A serious seller provides these without being pressed. When the first or the third is missing, the used machine is treated as being in unknown condition, whatever the price.

When each option wins

New wins when the period of use is long, the tonnage high, the rock abrasive, the site remote, and when the project schedule can absorb the manufacturing lead time. It is also the default when the crusher has to be sized precisely for the feed and throughput — see how to size a primary crusher.

Rebuilt wins when lead time is short, the budget constrained, the model common and well supported, and when the rebuild report is complete. It is often the best compromise for a standard-size secondary or tertiary.

Used wins for temporary use, a standby crusher, low tonnage or a short-life project — provided there is an independent inspection before purchase and a realistic provision for refurbishment and compliance.

The traps of buying used

• A discontinued model whose wear parts have to be custom-made at every changeout.
• A motor or electrical equipment of a different voltage or standard, to be replaced.
• Anchor dimensions that do not match the existing structure, discovered at installation.
• Transport from a distant site that costs a significant share of the machine's price.
• A "rebuild" with no report, no measurements and no warranty — that is a used machine at a rebuilt price.

The decision grid in six questions

1. How much lead time can the project absorb before production?
2. How many hours per year must the machine produce, and for how many years?
3. What does an hour of downtime cost on this site?
4. Is the model supported by its manufacturer, with parts available?
5. Is the condition documented by measurements, or merely asserted?
6. Who carries the risk if the machine does not deliver its performance — the seller, or you?

Answering those six questions in writing puts the three options on a comparable footing. That is what we do in our equipment sales and supply service: selecting the option, inspecting rebuilt or used equipment on site, checking interfaces before purchase, then installation and supply of wear parts over the service life.

Frequently asked questions

Is a rebuild by an independent shop as good as the manufacturer's? It can be, if the shop documents its work with the same measurements and provides a warranty. The difference often lies in access to genuine parts and to the manufacturer's tolerances.

Can a used crusher be inspected before buying? Yes, and it must be: an on-site inspection by someone independent of the seller, with a written report, before any commitment. Its cost is marginal compared with the risk it covers.

Can a used crusher come with a warranty? Some sellers offer a short warranty on specific components. It is worth what the seller is worth and exactly what it covers — to be read before, not after.
