Crusher Hire Costs: What a Quarry Owner Should Actually Compare The short answer is that crusher hire is rarely quoted as a single number. A rate per hour or
The short answer is that crusher hire is rarely quoted as a single number. A rate per hour or per day is only the visible part of the contract, and the real cost is a combination of the machine rate, transport and setup, fuel, wear parts, power supply, and any royalty or cost-per-tonne clause. As a quarry director, your job is not to find the lowest hourly rate, but to identify which hire package has the smallest total cost for your specific rock, your site layout, and your production deadline.
Most hire quotes in mobile crushing are structured in one of two ways: a fixed fee per hour or per week, or a cost per tonne of finished material. Each model shifts risk in a different direction. An hourly rate puts the scheduling and efficiency risk on your shoulders — if the crusher is waiting for haul trucks, you are paying for idle time. A per-tonne rate moves that risk to the contractor, but the price per tonne is usually higher to cover their uncertainty about your feed conditions .
Before any comparison, establish the pay basis in writing. The missing inputs that every supplier needs from you are: the exact material type, its hardness and moisture content, the maximum feed size, the required final aggregate size range, and the tonnes per hour you aim to maintain . Without those numbers, any quote is an estimate that may change once the machine is on your site.
Break every quote into line items rather than accepting a bundled price. The main components are:
Use the table below as your comparison sheet. Do not accept a quote that leaves any of these rows blank; enter the supplier’s confirmed answer and verify it in the contract.
| Cost / contract item | What you must confirm | Why it matters | Supplier answer |
|---|---|---|---|
| Pay basis | Hourly, weekly, monthly, or per tonne | Determines who carries idle-time and productivity risk | confirm in writing |
| Mobilisation & demobilisation | Is transport invoiced separately or included? | Can exceed the base rate for remote sites | confirm with site address |
| Setup and commissioning time | Billed from machine arrival or from first production? | Setup can take several shifts on uneven ground | confirm with site survey |
| Fuel supply | Your cost or included in the rate? | Diesel cost varies by load factor and material abrasiveness | confirm with local fuel price |
| Wear parts and liners | Included in rate or charged per tonne? | Jaw and cone liners differ hugely between abrasive and soft rock | confirm with material test |
| Power supply | Electric connection available or diesel only? | Electric crushing is often cheaper per tonne but has higher setup cost | confirm with site power capacity |
| Operator certification | Does the operator know this exact model? | Inexperienced operation reduces throughput and accelerates wear | confirm with crew CV |
| Breakdown response | Maximum downtime before a replacement is supplied | A cheap rate is worthless if the unit is down for a week | confirm with response-time clause |
| Minimum term or tonnage | Penalties for early return or low production | Matches the hire term to your project schedule | confirm with contract terms |
Crusher hire stops making sense when your project runs continuously for more than a few months and the feed is consistent. If you have a permanent, stable source of rock and a fixed product line, the cumulative hire cost can exceed the ownership and operating cost of a machine over a two- to three-year period. Hire is also a poor fit when your site lacks the power, access roads, and crane capacity needed for safe mobilisation — the cost of temporary infrastructure can erase the savings of hiring.
There is also a productivity ceiling. A rental unit is set up and configured by the supplier, and you have limited control over its settings, wear item changes, and maintenance schedule. If your operation depends on a precise particle shape or a narrow gradation window, the inability to fine-tune the machine can produce reject material that a dedicated owned unit would not.
No credible hire cost estimate can be produced from a machine model alone. You need to provide the supplier with, at minimum:
If these are not defined, any published rate is a starting point for negotiation, not a commitment. A responsible supplier will quote a provisional figure with a clear condition that the rate is subject to revalidation once your feed sample is tested.
Typically the machine, the operator, and basic maintenance are included, but not always fuel, wear parts, transport, or screening equipment. Confirm each line item separately because suppliers structure their packages differently, and the absence of one clause can change your total cost by a meaningful margin .
Per-tonne pricing protects you from idle time, but the contractor charges a premium for that risk, so your final cost may be higher if the plant runs efficiently. Per-hour pricing is cheaper when the machine runs at high utilisation, but you absorb the cost of delays. Run a quick calculation using your expected production rate and planned working hours to compare the two before signing [FACT REVIEW REQUIRED].
Often not. A crushing circuit can require a pre-screen, a mobile screen, and several conveyors to close the loop, and each piece is quoted separately. Verify whether the rate covers a full process line or just the crusher body, and check whether conveyors are included in mobilisation costs.
Build your own comparison table with identical line items — base rate, transport, fuel, wear parts, operator, and downtime response. Ask every supplier to complete the same format, and exclude any quote that will not separate its costs. The lowest total for your defined feed and output is the economically rational choice, not the lowest hourly figure.
Your contract should specify a maximum response time and a right to a replacement unit if downtime exceeds a set number of hours. Never accept a hire agreement without a defined breakdown clause, because a low daily rate on an unreliable machine is more expensive than a higher rate on a machine that holds its schedule.
