150-250 TPH River Stone Crushing Project in Timor-Leste
Client Overview
Our client, a leading construction company in Timor-Leste, needed a reliable 150-250TPH sand and gravel production line to process river stones for infrastructure projects. The challenge was to achieve high productivity while maintaining excellent particle shape for concrete and road construction.
Project Background
The project required:
- Material: River stone (medium hardness, high abrasiveness)
- Output: 150-250 tons per hour
- Final Products: 0-5mm (sand), 5-10mm, 10-20mm, and 20-30mm aggregates
- Application: Construction, concrete, and road building
Challenges
- Abrasive material: River stone wears down equipment quickly.
- High production demand: Stable 150-250TPH output.
- Particle shape requirements: Well-graded, cubic aggregates for strong concrete.
- Compact space: The plant needed a streamlined layout.
Solution: Customized Crushing & Screening Line
Liming Heavy Industry designed a two-stage crushing + sand-making process, featuring our best-selling crushing equipment:
1. Primary Crushing – C6X Jaw Crusher
- Model: C6X160
- Capacity: 200-350TPH
- Role: Coarse crushing of large river stones (≤800mm) into smaller pieces (≤200mm).
- Advantages:
- High crushing efficiency with deep “V” crushing chamber.
- Durable cast steel frame and jaw plates for long service life.
- Low energy consumption with optimized kinematics.
2. Secondary Crushing – HPT Multi-cylinder Hydraulic Cone Crusher
- Model: HPT300
- Capacity: 120-250TPH
- Role: Further crushes mid-sized stones (≤200mm) into 10-30mm for high-quality aggregates.
- Advantages:
- Hydraulic adjustment and overload protection for stable output.
- Laminating crushing principle improves particle shape.
- Advanced PLC automation for easy operation.
3. Sand Making – VSI6X Sand Maker
- Model: VSI6X1150
- Capacity: 150-280TPH
- Role: Transforms 10-30mm aggregates into 0-5mm high-quality sand.
- Advantages:
- “Rock-on-rock” crushing reduces wear costs.
- Adjustable gradation for ideal fineness modulus.
- High sand yield with superior particle shape.
4. Screening & Washing – S5X Vibrating Screen & XSD Wheel Sand Washer
- Screener: S5X3075-3 (3-layer screening for precise gradation)
- Washer: XSD3620 (removes impurities, enhances sand quality)
Technical Highlights
- Intelligent Control System: Centralized PLC control ensures smooth operation.
- Dust Suppression: Eco-friendly design minimizes dust and noise.
- Wear-Resistant Parts: High-chromium blow bars, cone liners, and anvils extend machine life.
- Modular Design: Quick installation and flexible expansion.
Project Results
- Output Achieved: 230TPH (exceeding the client’s 250TPH target).
- Final Products: 0-5mm sand (30%), 5-10mm (25%), 10-20mm (25%), 20-30mm (20%).
- Running Costs Reduced: 20% lower wear costs vs. traditional crushers.
- Client ROI: Payback within 11 months due to high efficiency and low downtime.
Client Feedback
“Liming’s crushing solution exceeded our expectations. The C6X Jaw Crusher and HPT Cone Crusher handle river stone perfectly, and the VSI6X Sand Maker produces sand meeting international standards. The production line runs smoothly with minimal maintenance. We highly recommend Liming for large-scale crushing projects!”
