The issue with fixed crushing stations lies not in the initial quote itself, but in the costs *outside* that quote. Concrete foundations, steel structural platforms, installation and commissioning, and the misalignment between land lease terms and project timelines—none of these four items appear on the equipment list, yet they often consume more than half the budget of the main machinery unit and lose all residual value once the project ends. Mobile crushing stations take a straightforward approach: they eliminate these four expenses entirely. They require no foundations or steel platforms, are ready for operation as soon as power is connected on-site, and can be towed away immediately upon completion.
However, this advantage has clear limits. A mobile crushing station only achieves a truly lower cost-per-ton than a fixed line of the same specification if at least two of the following conditions are met: a project cycle of under three years, multiple work sites, or a short-term land lease. For projects involving continuous extraction at a single site for over five years, the fixed line remains 10–15% cheaper after costs are amortized.
The following section compares the financials of both options side-by-side in a single table.
I. Why fixed crushing stations seem "cheap to quote but expensive in the end"

1.1 Civil engineering foundations and steel structures
For a 150 t/h fixed production line, the combined cost of concrete foundations, steel structural platforms, and embedded anchor bolts ranges from 250,000 to 400,000 RMB. Construction takes 15–30 days, and equipment installation cannot begin until the concrete has fully cured. Financially, this expenditure is a "sunk cost": it cannot be moved with the equipment or resold at a discount when the project concludes.
1.2 Installation, commissioning, and project duration
Fixed lines require a full workflow—civil works, steel structure assembly, hoisting, electrical wiring, inpidual unit commissioning, and integrated system testing. It typically takes 3–6 months from site entry to stable output. During this period, there is zero production, yet costs for labor, machinery rental, and capital interest continue to accrue—representing a classic "hidden expense." In contrast, mobile crushing stations compress this setup period to under 24 hours.
1.3 Relocation means starting from scratch
"Relocating" a fixed crushing station actually entails dismantling, transport, rebuilding foundations, and re-installation. Each move causes 10–20 days of downtime, and the original foundation is simply scrapped. For short- to medium-term contracting projects, this implies repeated interruptions to equipment utilization—a cost that never appears in any price quotation, yet shows up clearly on the project schedule.
1.4 Mismatch Between Approvals and Site Lease Terms
Many aggregate and solid waste projects operate on leased land with terms of only two to three years. Pouring permanent foundations on such leased sites represents a classic case of capital mismatch: the investment payback period exceeds the duration of the land-use rights, leaving no residual value to be recovered upon exit.
II. Stationary vs. Mobile Crushing Stations: Cost Comparison at Equal Capacity
2.1 Cost Comparison Table (150 t/h Operating Scenario)
| Cost Item | Stationary Crushing Station | Mobile Crushing Station | Assessment of Difference |
|---|---|---|---|
| Equipment Unit | Baseline | Approx. +20%–30% (chassis, hydraulic outriggers, onboard electrical controls) | Mobile station is more expensive |
| Foundations & Steel Structures | RMB 250,000–400,000; 15–30 days for construction | 0 (no foundation or platform required) | Mobile station eliminates this cost entirely |
| Site Preparation | Leveling + hardening + drainage ditches + fencing | Only requires compacted areas for loading/unloading and stockpiling | Mobile station saves approx. 60%–70% |
| Installation to Stable Output | 3–6 months | Production starts within 24 hours of arrival (pre-assembled and tested at the factory) | Mobile station saves 2–6 months of lead time |
| Single Relocation | Dismantling + new foundation + re-installation; 10–20 days of downtime | Towed relocation; positioned within 2 hours on-site; full line resumes production in 1 day | Mobile station is an order of magnitude more efficient |
| Residual Asset Value After Relocation | Original foundation scrapped; non-recoverable | Chassis and main unit move with the plant | Mobile station incurs no residual loss |
| 3-Year Comprehensive Cost Per Ton | High (fixed investment must be amortized within the term) | Low (for terms <3 years and multi-site scenarios) | See Section 5 for boundary conditions |
Note on Scope: The "Assessment of Difference" column provides qualitative or range-based conclusions for the price comparison framework, helping to categorize cost items. Specific amounts fluctuate based on material lithology, target capacity, and logistics/tariffs by country; inpidual project calculations are required.

2.2 How to Interpret This Table
The deciding factor is not the "Equipment Unit" line, but the four lines below it. While the mobile crushing station is indeed more expensive in terms of the equipment unit itself, this price premium is controllable and estimable. In contrast, the additional costs associated with foundations, construction timelines, and relocation losses for stationary lines are fixed, unavoidable expenses that cannot be reduced through negotiation. If one compares only the initial cost figures, the conclusion regarding which is more cost-effective—a mobile crushing station or a fixed production line—will inevitably be incorrect.
III. Calculating the three cost savings of mobile crushing stations
3.1 Output gained through faster setup
A 150 t/h unit operating 12 hours a day can produce approximately 54,000 tons per month; with a gross profit of 15 yuan per ton on finished products, commencing production 2–6 months earlier results in a gross profit difference ranging from hundreds of thousands to over a million yuan. This factor alone often offsets the price difference between mobile crushing stations and fixed lines.
3.2 Equipment utilization gained through relocation efficiency
Relocating a fixed line requires 10–20 days of downtime, whereas a mobile crushing station can be positioned on-site in just 2 hours and resume full production within a day. The more work sites involved, the more pronounced this gap becomes—representing the mobile crushing station's strongest advantage in scenarios requiring rotation across multiple sites.
3.3 Capital structure benefits from eliminating foundation work
Savings extend beyond the 250,000–400,000 yuan in civil engineering costs to include the 15–30 days of construction time and associated capital costs that would otherwise be consumed. Capital expenditure shifts from a "one-time sunk cost" to a "relocatable, reinvestable mobile asset"—a distinction that is particularly critical for projects involving leased land or phased production.
IV. Comparison of Main Parameters and Capacities for Mobile Crushing Stations
| Station Type | Model | Main Unit | Max. Feed Size (mm) | Nominal Capacity (t/h) | Installed Power (kW) | Transport Dimensions (m) |
|---|---|---|---|---|---|---|
| Mobile Jaw Crushing Station | YDPZ-750 | PE500×750 | 425 | 40–110 | 90–132 | 12.5×2.8×3.6 |
| Mobile Jaw Crushing Station | YDPZ-900 | PE600×900 | 500 | 80–200 | 110–160 | 13.8×3.0×3.9 |
| Mobile Jaw Crushing Station | YDPZ-1060 | PE750×1060 | 630 | 110–320 | 132–180 | 14.6×3.0×3.9 |
| Mobile Impact Crushing Station | YDPZ-1214 | PF-1214 | 350 | 80–160 | 160–200 | 14.2×3.0×3.9 |
| Mobile Cone Crushing Station | YDPZ-900C | PYB900 | 115 | 50–90 | 110–150 | 13.0×2.8×3.6 |
| Mobile Sand-Making Station | YDPZ-9526 | VSI-9526 | 50 | 100–260 | 200–320 | 14.5×3.2×4.0 |
| Mobile Screening Station | YDPZ-2160 | YK2160 | — | 100–300 | 30–45 | 11.8×2.6×3.4 |
Note: Nominal capacity is based on limestone (bulk density: 1.6 t/m³). When processing hard rock such as granite or basalt, the actual capacity must be calculated by applying a rock-specific coefficient; additionally, the capacity of the entire production line is limited by the bottleneck component. When selecting equipment, please verify specifications based on the actual material properties rather than relying solely on nominal values.

V. Three Boundary Conditions: When Mobile Crushing Stations Are Actually More Expensive
Mobile crushing stations are not a universal substitute for fixed production lines. Choosing a mobile station results in long-term cost disadvantages in the following three scenarios:
1. Single mining site with continuous operation exceeding 5 years. Since the equipment is never relocated, the initial fixed investment has ample time to be amortized; fixed lines offer a 10%–15% lower cost per ton, meaning the price premium paid for the mobile chassis and hydraulic systems cannot be recouped.
2. Long-term demand exceeding 500 t/h. Constraints regarding chassis load capacity, onboard electrical controls, and highway transport dimensions become restrictive; the combined investment for multiple mobile units operating in parallel is usually higher than that of a single fixed line.
3. Ownership of the site for long-term use combined with access to a stable, low-cost power grid. The benefits of eliminating foundation and steel structure costs are lost, while fixed lines offer lower unit electricity costs.
VI. FAQ
Q1: Mobile crushing stations are more expensive than fixed ones; can the extra cost be recovered?
Yes, but it depends on the project duration and the number of relocations. While the mobile station unit itself costs about 20%–30% more, it eliminates expenses such as 250,000–400,000 RMB for foundation steel structures and site paving, as well as the 3–6 month construction period. Based on a capacity of 150 t/h and 12 hours of daily operation, the gross profit generated by starting production two months earlier is sufficient to cover the price difference; if the project requires more than one relocation, the advantage becomes even greater.
Q2: Can the production capacity of a mobile crushing station match that of a fixed line?
Yes. The main crushing units mounted on the mobile station are the same models used in fixed lines (e.g., PE600×900, PE750×1060, PF-1214, PYB900), featuring identical crushing chamber designs; any difference in capacity stems solely from the continuity of the material feed. When equipped with standard vibrating feeders and hoppers, the feeding rate matches that of fixed lines, and the deviation in total line capacity is typically kept within 5%—only the chassis is mobile, not the main crushing unit itself.
Q3: Does "foundation-free" mean absolutely no foundation work is required? What site conditions are necessary?
No concrete foundation or embedded anchor bolts are required; however, the site must still meet two conditions: first, the load-bearing capacity and surface flatness must satisfy the requirements for supporting the outriggers (compacted graded aggregate can be used to prevent subsidence on soft ground); and second, there must be sufficient space for material stockpiling and vehicle maneuvering—for the four-unit combined model, an operating area of at least 30 m × 50 m is recommended. If the site consists of fill soil or has high moisture content, we will provide recommendations for ground treatment and outrigger pad selection along with the proposal.
