Mobile vs Stationary Batching Plants: Which Is Right for Your Australian Project?
Quick answer: Choose a mobile plant if you work across multiple sites, need flexibility, or have lower volume requirements ($80k–$350k). Choose a stationary plant if you have a permanent production facility, need high output, or are serving a fixed market ($250k–$1.2M+).

Mobile vs Stationary: Quick Comparison
Here's the high-level difference at a glance before we dive deep into every factor.
| Comparison Factor | Mobile Plant | Stationary Plant |
|---|---|---|
| Upfront cost (installed) | $80k – $350k | $250k – $1.2M+ |
| Typical output | 20 – 80 m³/hr | 60 – 180+ m³/hr |
| Setup time | 1–3 days (mobile) to 1–2 weeks (towable) | 4–12 weeks |
| Foundation required | Minimal — often just compacted ground | Extensive reinforced concrete slab |
| Relocation cost | $3k–$15k per move | Prohibitive — essentially permanent |
| Best for | Multiple sites, remote projects, contractors | Fixed production facility, high volume |
| Automation potential | Basic to semi-automatic | Semi to fully automatic |
🚚 Mobile Batching Plant
Designed to move between sites. Mounted on a chassis with axles — towable by truck.
- ✓ Relocate between projects
- ✓ Lower upfront investment
- ✓ Minimal foundations required
- ✓ Faster setup (days, not weeks)
- ✗ Lower maximum output
- ✗ Less automation available
- ✗ Higher cost per m³ over time
🏭 Stationary Batching Plant
Permanent installation designed for high-volume, continuous production.
- ✓ Highest output capacity (100–180+ m³/hr)
- ✓ Lower cost per m³ at volume
- ✓ Full automation available
- ✓ Better long-term ROI at high utilisation
- ✗ High upfront capital
- ✗ Extensive foundations required ($30k–$100k)
- ✗ Cannot be relocated economically
Cost Comparison: Mobile vs Stationary
Upfront cost is the most obvious difference, but let's look at the full picture including installation and operating costs.
| Cost Component | Mobile Plant (50 m³/hr) | Stationary Plant (80 m³/hr) |
|---|---|---|
| Equipment only | $120k–$220k | $300k–$500k |
| Delivery | $5k–$15k | $8k–$25k |
| Foundations | $5k–$15k (compacted pad) | $30k–$80k (reinforced slab) |
| Electrical installation | $8k–$20k | $25k–$60k |
| Silos (if not included) | $10k–$25k | $20k–$60k (2–3 silos) |
| Commissioning | $3k–$8k | $8k–$20k |
| Total installed | $151k–$303k | $391k–$745k |
Key insight: A stationary plant typically costs 2–3x more upfront than a mobile plant of comparable capacity. But at high utilisation, the stationary plant's cost per cubic metre can be 30–50% lower due to efficiency and automation.
Capacity & Output: What Can Each Actually Produce?
Output capacity is measured in cubic metres per hour (m³/hr). Here's what's realistic for each type.
Mobile Plant Outputs
- Small mobile: 20–40 m³/hr
- Mid-size mobile: 40–60 m³/hr
- Large mobile: 60–80 m³/hr (rare)
Daily production (8 hours): 160–640 m³
Stationary Plant Outputs
- Compact stationary: 60–100 m³/hr
- Standard stationary: 100–140 m³/hr
- Large stationary: 140–180+ m³/hr
Daily production (8 hours): 480–1,440+ m³
💡 The catch: Mobile plants often have lower actual output than their rated capacity because they're frequently moved and set up. Stationary plants can run consistently at 80-90% of rated capacity.
Setup & Installation: Time, Complexity, and Hidden Work
This is where mobile plants have a massive advantage — but there are trade-offs.
| Factor | Mobile Plant | Stationary Plant |
|---|---|---|
| Time from delivery to production | 1–5 days | 4–12 weeks |
| Ground preparation required | Compacted level area | Engineered foundations, rebar, concrete pour |
| Crane required for assembly | Sometimes (silo placement) | Always (mixer unit, silos, conveyors) |
| Electrical complexity | Single connection point | Multiple panels, transformer often required |
| Permits typically required | Minimal (traffic for delivery) | Building, environmental, council approval |
⚠️ Most underestimated difference: Stationary plants require significant site works before any equipment arrives. Foundation curing alone takes 14–28 days before you can install anything on top. Mobile plants can be running on compacted ground within a week of delivery.

Mobile plants are called "mobile" for a reason. But how often do you actually need to move? This determines the value of mobility.
Mobile Plant Mobility
True mobile plants are road-legal with axles, lights, and brakes. They can be towed by a semi-trailer between sites. Relocation cost: $3k–$15k depending on distance. Time to relocate: 1–2 days disassembly + 1–2 days setup at new site.
Best for: Contractors working on multiple projects per year (3+ moves). Remote infrastructure projects (mines, roads, dams). Companies that want to sell or relocate the plant later.
Stationary Plant (Im)mobility
Stationary plants are not designed to move. Relocating one costs $50k–$200k+ and effectively requires rebuilding. Most stationary plants stay in place for their entire 25+ year lifespan.
Best for: Permanent ready-mix operations. Precast yards. Long-term infrastructure projects (5+ years at same site).
Total Cost of Ownership: 5-Year Comparison
Upfront cost is only part of the story. Here's how mobile and stationary compare over 5 years of operation.
| Cost Category (5 years) | Mobile Plant | Stationary Plant |
|---|---|---|
| Initial purchase + install | $220k | $550k |
| Annual maintenance (wear parts) | $12k/year ($60k total) | $18k/year ($90k total) |
| Operating cost per m³ (labour + power) | $8–12/m³ | $5–8/m³ |
| Relocation costs (if 2 moves) | $15k | N/A (permanent) |
| Depreciation (5 years) | $100k | $250k |
| Resale value after 5 years | $80k–$120k | $200k–$350k |
| Net 5-year cost (after resale) | $315k–$375k | $540k–$690k |
Break-even analysis: A stationary plant becomes more cost-effective than a mobile plant when annual production exceeds 25,000–35,000 m³ per year. Below that volume, the mobile plant's lower upfront cost wins on total cost of ownership.

Frequently Asked Questions
Can a mobile plant be used as a stationary plant?
Yes — many buyers purchase a mobile plant and keep it in one location permanently. You're paying extra for mobility features you don't use, but the lower upfront cost still makes sense for smaller volumes.
Can a stationary plant ever be moved?
Theoretically yes, but practically no. Relocating a stationary plant costs $50k–$200k+ and requires re-engineering foundations, electrical, and site works. Stationary plants should be considered permanent.
Which has better resale value?
Stationary plants typically hold value better as permanent industrial assets. Mobile plants depreciate faster but are easier to sell to a wider range of buyers (contractors, hire companies, international buyers).
What about compact plants — where do they fit?
Compact stationary plants are a hybrid — smaller footprint than full stationary, higher output than mobile, but still require foundations and are not mobile. They're excellent for urban sites with space constraints.
