Customer Profile
A Mongolian construction materials company sought a high-yield sand production line to process locally sourced river pebbles into high-quality aggregates for infrastructure projects.
Project Overview
Location: Mongolia
Material: River pebble (hardness ~7 Mohs)
Capacity: 200–300 TPH
Final Products: 0–5mm, 5–10mm, 10–20mm sand and aggregates
Challenges
- Hard Material: River pebble’s high abrasiveness demanded wear-resistant equipment.
- Yield & Gradation: Required uniform particle size distribution for commercial sand.
- Dust Control: Needed eco-friendly solutions to comply with local regulations.
Solution: Liming Heavy Industry’s Customized Configuration
- Primary Crushing:
- C6X Jaw Crusher
- Role: Coarse crushing of large pebbles (<630mm).
- Advantage: High crushing ratio, durable toggle plate.
- Secondary Crushing:
- HST Single-Cylinder Hydraulic Cone Crusher
- Role: Medium/fine crushing to 40–70mm.
- Advantage: Automated hydraulic adjustment, low downtime.
- Sand Making:
- VSI6X Impact Crusher (Sand Maker)
- Role: Shaping ≤5mm sand with cubic particles.
- Advantage: Patented rotor, 30% longer lifespan than conventional models.
- Screening:
- S5X Vibrating Screen
- Role: Precise grading into 3 sizes.
- Advantage: Multi-layer design, high screening efficiency.
- Auxiliary:
- Belt conveyors, dust removal system (pulse bag filter), and centralized control.
Technical Highlights
- Intelligent Control: PLC system enabled real-time monitoring of production and faults.
- Wear Resistance: VSI6X’s tungsten carbide rotor and HST’s manganese liner reduced replacement costs.
- Green Production: Dust suppression achieved 99% filtration efficiency.
Project Results
- Capacity: Steady 250TPH output (exceeding client’s 200TPH target).
- Product Quality: Sand met ASTM C33 standards for concrete.
- Cost Savings: 18% lower operational costs vs. traditional solutions.
