A standard railway gondola holds ≈ 69 tonnes of crushed stone — the minimum batch HKC ships. By volume that is roughly 42–50 m³ depending on fraction.
Volume of 69 tonnes by fraction
How many cubic metres 69 t (one wagon) occupy for each HKC diabase fraction. Calculation: 69 ÷ bulk density.
| Fraction | Bulk density, t/m³ | Volume of 69 t (1 wagon), m³ |
|---|---|---|
| 5-10 mm | 1,52 | ≈ 45 m³ |
| 5-20 mm | 1,48 | ≈ 47 m³ |
| 10-20 mm | 1,45 | ≈ 48 m³ |
| 20-40 mm | 1,42 | ≈ 49 m³ |
| 25-60 mm | 1,40 | ≈ 49 m³ |
| 40-70 mm | 1,38 | ≈ 50 m³ |
| 0-5 mm (screenings) | 1,55 | ≈ 45 m³ |
| 0-40 mm (mix) | 1,60 | ≈ 43 m³ |
| 0-70 mm (mix) | 1,62 | ≈ 43 m³ |
| 0-80 mm (mix) | 1,65 | ≈ 42 m³ |
Enter volume and fraction — we count wagons at 69 t.
How much in a truck (approximate)
HKC ships by rail; truck figures are for reference. Volume = payload ÷ bulk density.
| Payload | Volume, m³ (≈) |
|---|---|
| 10 t | ≈ 6.5–7 m³ |
| 15 t | ≈ 10–11 m³ |
| 20 t | ≈ 13–14 m³ |
| 25 t | ≈ 16–18 m³ |

Frequently asked questions
How many tonnes of crushed stone in one railway wagon?
A standard gondola holds about 69 tonnes — the minimum batch HKC ships. By volume that is roughly 42–50 m³ depending on fraction.
How many cubic metres in a wagon?
About 42–50 m³. Calculation: 69 t ÷ bulk density. E.g. 20-40 mm (1.42) → ≈ 49 m³; 40-70 mm (1.38) → ≈ 50 m³. See the table above.
What is the minimum shipment?
Minimum — 1 railway wagon (≈69 t). Shipping is from Bershogyr station across Kazakhstan. Smaller volumes are not shipped by rail.
How much crushed stone in a truck?
Depends on payload and body volume. Roughly: 10 t ≈ 6.5–7 m³, 20 t ≈ 13–14 m³, 25 t ≈ 16–18 m³. HKC ships by rail; trucking is arranged separately on request.
How do I count wagons for my volume?
Divide tonnage by 69 t and round up. E.g. 500 t → 8 wagons. Easier — use the calculator.
