Set the Crusher’s Workload and Useful Life
Start with the crusher’s expected annual operating hours and service life. Both affect cost per ton. Use production records to estimate scheduled shifts, planned downtime, and actual utilization. Rated hours aren’t the same as productive hours.
Next, define the material, feed size, and target product size. These conditions help you check whether the crusher can meet your required throughput and estimate total production over its useful life.
Use maintenance logs and site conditions to project the service life of wear parts such as liners, mantles, and jaws. Abrasive feed and operating practices can shorten replacement intervals and reduce lifetime tonnage.
Before inspecting or servicing the crusher, follow site lockout procedures and the manufacturer’s safety instructions.
Add the Purchase Price and Setup Costs
Start with the crusher’s purchase price, including the options and attachments you need. Check the quote carefully to confirm what’s included and what’s charged separately.
Add freight, rigging, commissioning, and installation costs to account for getting the machine to the site and ready to run.
Include site preparation costs, such as foundations, access roads, and electrical upgrades. Base these estimates on contractor quotes or measured quantities, and confirm that the work suits the crusher’s layout and operating requirements.
Before inspecting or working around equipment, follow site safety procedures and isolate it where required.
Equipment Purchase Price
Before estimating a crusher’s total cost of ownership, add the purchase price to the costs of getting the machine installed and ready to run.
Compare quotes for equivalent models, checking capacity, feed size, drive power, wear materials, and included controls. A lower price may reflect a different configuration or leave essential items out of the quote.
Prices for steel, motors, and other components can change, so record the date of each quote and confirm how long it remains valid.
Check the supplier’s service history, parts availability, and references from operations using similar equipment.
Include taxes, financing fees, commissioning, and any required electrical or foundation work in the initial capital estimate.
Separate essential equipment from optional upgrades, and document the assumptions behind each bid. This makes comparisons more reliable and gives you a clear basis for revising the budget when specifications change.
Delivery and Installation
What’ll it cost to move the crusher from the supplier’s yard to its operating position? Include freight, permits, escorts, and oversize-load fees in the delivered cost. The transport plan depends on the crusher’s dimensions and weight, the haul distance, route restrictions, and whether the load needs a lowboy or modular trailer.
Get an itemized carrier quote, and confirm who’s responsible for unloading, access preparation, and any delays caused by site conditions.
Installation costs may include labor, crane or rigging hire, commissioning, and operator training. Ask the supplier to list crew rates, estimated hours, travel charges, and exactly what the installation covers.
Add these costs to the equipment price before comparing the total with your budget. Confirm in writing when the warranty starts and whether commissioning is required.
Site Preparation Costs
After the crusher is delivered, site preparation can add significantly to the purchase and installation budget. Price clearing and demolition, including vegetation removal and haul-off. Check that access roads are wide enough and have adequate bearing capacity for delivery trucks, cranes, service vehicles, and other equipment.
Design the foundation for the crusher’s operating weight and dynamic loads, following the manufacturer’s installation requirements. Include excavation, drainage, engineered fill, and soil compaction in the estimate. Field density testing can help confirm that the prepared ground meets the project’s bearing requirements.
Also account for concrete, reinforcement, utility connections, permits, and contractor mobilization. Include these costs in the total acquisition budget. Cutting corners on site preparation can lead to settlement, misalignment, downtime, and expensive repairs.
Before work begins, confirm site conditions and foundation details with the project engineer and equipment supplier. For any inspection or work near construction equipment, follow site procedures and keep personnel clear of suspended loads and moving machinery.
Calculate Crusher Fuel, Power, and Labor Costs
To calculate crusher fuel, power, and labor costs, use records from the same operating period. Multiply measured fuel use per operating hour by the fuel price per unit.
For electricity, use metered kilowatt-hours and your utility rate; include only the equipment covered by that meter.
Calculate labor by multiplying crew hours by each worker’s loaded wage rate, including applicable payroll costs.
Divide each total by actual crusher operating hours to compare costs on a consistent basis.
Keep standby time separate, and check that fuel, power, and labor records cover the same shifts and equipment.
Fuel Consumption Costs
Fuel, electricity, and labor can account for a significant share of a crusher’s operating costs. Track each separately using actual site data.
For fuel, record the liters used and productive operating hours over a representative shift. Divide liters by productive hours to calculate fuel consumption per hour, then multiply by your delivered fuel price to estimate the hourly fuel cost.
Record idle time separately. An engine can burn fuel while the plant isn’t processing material, so include idle hours when reviewing total fuel use. Compare results across shifts, feed conditions, and equipment settings to spot changes and identify avoidable idling.
If consumption rises unexpectedly, check the operating records and arrange an inspection. Follow site procedures and isolate equipment before any maintenance or inspection.
Reducing unnecessary fuel use can lower cost per tonne and help reduce emissions.
Electricity and Power
For electric crushers, calculate power cost from metered kilowatt-hours (kWh) and the rate you actually pay. Use the full tariff, including demand charges, time-of-use rates, and applicable fees.
Track kWh per ton across different feed materials, settings, and production rates to spot inefficient operation.
Use readings from the crusher’s power meter or control system. A motor nameplate shows rated capacity, not actual power draw.
For mobile plants, include generator fuel use and conversion losses, or account for the cost of a grid connection.
If you use battery storage, include charging losses and battery efficiency.
Renewable power can reduce purchased electricity, but include the cost of the equipment and financing when comparing options.
Before inspecting meters, wiring, or electrical equipment, isolate the power source and follow site lockout procedures.
Labor and Operating Hours
Labor cost is driven by the hours people spend operating and supporting the crusher—not just the hours the machine runs. Record operator, loader, mechanic, and supervisor hours by shift, then apply each role’s fully burdened labor rate, including payroll taxes and benefits.
Separate productive crushing time from setup, cleanup, maintenance, and downtime. That breakdown shows where labor is going and helps you calculate labor cost per ton.
Compare scheduled and actual operating hours with fuel and power use: equipment sitting idle can consume labor and energy without adding production.
Include time for training and required operator safety coverage. Track the labor involved in dust control and emissions management, too, so your production targets account for the work needed to meet site requirements.
When inspecting or maintaining equipment, follow site procedures and lockout/tagout requirements before work begins.
Budget for Crusher Maintenance and Wear Parts
Maintenance and wear parts can make up a significant share of a crusher’s lifetime operating cost. Include them in the ownership budget, not just the purchase price. Track liner, jaw plate, mantle, and screen media use against tons processed, material abrasiveness, and feed size.
Treat supplier estimates for service life as a starting point, then adjust them using your own operating records.
For each parts replacement, account for the part, labor, freight, and any required tooling. Plan maintenance around the manufacturer’s intervals and inspection findings, and budget for lubricants, filters, belts, and major component overhauls.
Review maintenance cost per ton regularly, and revise forecasts when throughput or material conditions change.
Before any inspection or maintenance, follow site lockout procedures and the equipment manufacturer’s safety instructions. Never work on a crusher or screen until it’s isolated and secured.
Estimate Crusher Downtime and Lost Production Costs
Crusher downtime costs more than the repair bill. Estimate lost production by multiplying the hours the crusher is unavailable by its realistic hourly throughput and the contribution margin per ton. Use actual operating data rather than nameplate capacity, and account for feed size, material hardness, operating rate, and normal production variability.
Review planned and unplanned outage records separately. Classify downtime by cause, such as mechanical failure, liner change, or an upstream or downstream stoppage. Include time spent restarting and any backlog that prevents the plant from recovering production afterward. A crusher may be back in operation while the wider circuit is still catching up.
For each outage, add the costs that can be tied to it: labor, contractors, rental equipment, and parts. Scheduling maintenance during lower-demand periods can reduce lost production. Keeping critical spares on hand can also shorten repair time, provided parts are suitable and stored so they’re ready when needed.
Before inspecting or repairing a crusher, isolate and lock out all energy sources, verify the equipment is safe to work on, and follow site procedures.
Compare Crusher Ownership Cost per Ton
Once you’ve estimated the cost of outages, compare crushers by total ownership cost per saleable ton—not purchase price alone. Include acquisition, financing, installation, energy, labor, wear parts, maintenance, downtime, and disposal over the planned service life. Divide those costs by the tons that meet your saleable product requirements, accounting for availability, throughput, and yield.
Keep the comparison fair: use the same operating hours, feed characteristics, production targets, and product requirements for each machine. Include water, dust-control, and emissions costs where they apply. Then check the result against market demand. A low cost per ton is no advantage if the crusher can’t reliably produce the required gradations and volumes.
Test how the result changes with energy prices, liner life, and utilization. Use realistic assumptions from your own operation, not best-case figures. When inspecting equipment or carrying out maintenance, follow site procedures, isolate energy sources, and verify the machine is safe before work begins.
Conclusion
To calculate your crusher’s true cost per ton, account for the work it will do and how long it will remain productive. Include the purchase price, delivery and setup, fuel or electricity, labor, maintenance, wear parts, and downtime. Then divide the total ownership and operating costs by the saleable tons produced—not the crusher’s rated capacity. Use the same production assumptions when comparing machines or operating options.
Keep a record of operating hours, tonnage, fuel or power use, repairs, and lost production. Review the estimate as feed material, operating conditions, and maintenance needs change. When inspecting or servicing the crusher, follow lockout procedures and the manufacturer’s safety instructions; never work on equipment that could start or move unexpectedly.
