How Much Does a Flour Mill Cost? Equipment and Turnkey Prices by Capacity
Realistic cost ranges for wheat flour mills from 20 to 500 t/d — equipment only versus turnkey, what drives the price up or down, and the six cost lines buyers forget to budget.

Key takeaways
- Equipment is 35–45% of project cost. Building, electrical, installation and working capital make up the rest.
- 20 t/d: USD 130k–190k turnkey. 60 t/d: USD 380k–560k. 200 t/d: USD 1.2–1.8M.
- Two quotations 30% apart usually differ in flow sheet passages, sifter area and cleaning completeness — not in margin.
Equipment cost by capacity
| Capacity | Equipment range (USD) | Notes |
|---|---|---|
| 200–450 kg/h unit | 8,000–25,000 | Single frame, integrated |
| 2–5 t/d | 25,000–55,000 | Double or five-mill unit |
| 16–18 t/d | 65,000–95,000 | Five-mill with cleaning |
| 20 t/d | 85,000–125,000 | 6FTDP-20, 3B2M |
| 30 t/d | 120,000–175,000 | 6FTDP-30, 4B4M |
| 40 t/d | 170,000–250,000 | 3B4M1S with purifier |
| 60 t/d | 240,000–350,000 | 4B5M1S1T |
| 100 t/d | 400,000–580,000 | Storey-typed |
| 200 t/d | 780,000–1,150,000 | Full turnkey plant |
| 300 t/d | 1,250,000–1,850,000 | Full turnkey plant |
| 500 t/d | 2,100,000–3,100,000 | Full turnkey plant |
Turnkey cost (building included)
| Capacity | Turnkey (USD) | Working capital |
|---|---|---|
| 20 t/d | 130,000–190,000 | 20,000–32,000 |
| 30 t/d | 185,000–265,000 | 28,000–45,000 |
| 60 t/d | 380,000–560,000 | 58,000–95,000 |
| 100 t/d | 620,000–900,000 | 95,000–150,000 |
| 200 t/d | 1,200,000–1,800,000 | 185,000–300,000 |
| 300 t/d | 1,900,000–2,800,000 | 290,000–470,000 |
| 500 t/d | 3,200,000–4,700,000 | 490,000–790,000 |
Ranges are wide because building cost varies by a factor of three between countries.
What pushes the price up
| Factor | Cost impact |
|---|---|
| Wet cleaning instead of dry | +8–12% |
| Purifier bank | +6–10% |
| Extra break passage | +7–8% |
| Stainless contact surfaces | +12–18% |
| Pneumatic conveying instead of bucket elevators | +10–15% |
| Storey tower instead of shed | +25–40% |
| High-altitude or tropical de-rating | +5–8% |
| CE certification | +6–12% |
What pulls it down
| Factor | Saving |
|---|---|
| Fewer passages (with extraction cost) | −12–20% |
| Standard grey iron instead of stainless trim | −8–12% |
| Local building instead of prefabricated | −10–25% |
| Manual instead of automatic dampening | −3–5% |
| Single shift design (smaller intake) | −5–8% |
The six forgotten lines
- Transformer and switchgear — USD 30,000–150,000 at 100–200 t/d
- Effluent treatment — USD 15,000–40,000 if wet cleaning
- Spare parts stocking — 2–3% of equipment value
- Working capital — 12–18% of project cost
- Import duty and freight — 5–25% depending on country
- Commissioning travel and accommodation — USD 8,000–25,000
How to compare quotations
Never compare totals. Compare these five things on the same page:
| Item | Why it matters |
|---|---|
| Flow sheet passages | Directly sets extraction and revenue |
| Sifter area (m²) | Caps classification capacity |
| Cleaning machine count | Determines achievable ash |
| Installed power | Determines transformer and running cost |
| Building dimensions | Determines civil cost |
Two quotations that differ by 30% and match on all five are a genuine price difference. Two that differ by 30% and differ on three of the five are different products.
