1. Project Overview (Russia / Kazakhstan)
This 250 TPH mobile crushing and screening line was supplied for a granite quarry in Russia/Kazakhstan, where the customer needed:
- Reliable operation in cold climate
- High-quality aggregates for concrete and asphalt
- Easy relocation between quarry benches
- Low operating cost and simplified maintenance
The final products required were:
- 0–5 mm
- 5–10 mm
- 10–20 mm
- 20–31.5 mm
The customer previously used a fixed plant but wanted a mobile line to reduce hauling distance and fuel consumption.
2. Material & Site Conditions
- Material: Hard granite (120–180 MPa)
- Feed Size: Up to 600 mm blasted rock
- Required Capacity: 230–250 TPH
- Working Temperature: –10°C to –20°C
- Operation Mode: 10–12 hours per day, 6 days per week
- Electricity: Diesel generator set (common in CIS regions)
The system was designed to operate stably in low-temperature climates and uneven terrain.
3. Selected Mobile Plant Configuration
(1) Primary Mobile Jaw Crusher
- Feed opening: 1060×700 mm
- CSS: 120–150 mm
- Output: 0–150 / 0–200 mm
- Designed for hard granite
- Fuel consumption optimized under 35–40 L/h
The jaw unit handles large stones directly and prepares uniform feed for the cone crusher.
(2) Secondary Mobile Cone Crusher (Closed Circuit)
- Medium/fine chamber for granite
- CSS: 14–22 mm
- Real capacity: 250–300 TPH
- Hydraulic adjustment and overload protection
This unit ensures excellent cubicity for concrete and asphalt applications—important for Russian/GOST standards.
(3) 3-Deck Mobile Screening Plant
- Top deck: 31.5 mm
- Middle deck: 20 mm
- Bottom deck: 10 mm
- Outputs: 0–5 / 5–10 / 10–20 / 20–31.5 mm
Oversize returns to the cone crusher, forming a stable closed circuit.
4. Process Flow (Simple, Clear Layout)
Excavator → Mobile Jaw Crusher → Mobile Cone Crusher → 3-Deck Screen → Stockpiles
- No heavy foundations
- Quick relocation (1–2 hours)
- Reduced internal trucking distance
- Suitable for multi-bench granite quarries
This simple process is very familiar to CIS operators, making training easier.
5. Production Performance (Real Numbers)
During commissioning and initial operation:
| Fraction | Output (TPH) | Notes |
|---|---|---|
| 0–5 mm | 45–55 | High-quality M-sand |
| 5–10 mm | 40–50 | Clean, stable grading |
| 10–20 mm | 80–90 | Main volume |
| 20–31.5 mm | 60–70 | For asphalt/base |
Total stable capacity: 230–250 TPH
Fuel Consumption
- Jaw crusher: 35–40 L/h
- Cone crusher: 30–35 L/h
- Screen & conveyors: 15–20 L/h
Combined: approx. 80–95 L/h (depending on material hardness and CSS)
6. Why Russian/Kazakh Customers Prefer This System
✔ Works in Low Temperature
Hydraulic systems and engines selected for cold-country use.
✔ Easy Maintenance
Common spare parts, simple liner replacement, easy access to service points.
✔ Lower Cost per Ton
Less truck movement, less civil work, stable closed-circuit crushing.
✔ Strong Mobility
Can move with the face, suitable for quarries with multiple ledges.
✔ Operator-Friendly
Russian-language labels or control interface available.
7. Delivery & Installation
- Production Time: 25–35 days
- Shipping: China → Russia/Kazakhstan (rail or sea + truck)
- Installation: 3–5 days
- Training: Equipment operation + daily maintenance + troubleshooting
Spare parts are stocked in China with quick shipping to CIS regions.
8. Optional Add-Ons for CIS Market
- Additional cone or VSI for more fines
- Pre-screening/scalper for dirty material
- Dust suppression system
- Winter protection / enclosure kit
- Russian-language control panel labels
