River Stone Crushing Plant in Papua New Guinea
Customer Profile
Location: Papua New Guinea
Material: River stone (high hardness, abrasive)
Production Requirement: 50-100 tons per hour
Application: Construction sand and gravel for local infrastructure projects.
Project Overview
The client needed a reliable sand and gravel production line to process river stone into high-quality aggregates for road construction and concrete production. Key challenges included material hardness, portability requirements, and consistent output sizing.
Challenges
- Hard & Abrasive Material: River stone’s high silica content demanded wear-resistant equipment.
- Throughput Stability: Required steady 50-100tph output with low downtime.
- Space Constraints: Semi-mobile setup preferred for remote site flexibility.
Solution by Liming Heavy Industry
Equipment Configuration & Advantages:
- PE600×900 Jaw Crusher (Primary Crushing)
- Role: Coarse crushing of river stone to ≤150mm.
- Advantage: Deep crushing chamber and high torque motor for hard rock.
- HPT300 Hydraulic Cone Crusher (Secondary Crushing)
- Role: Further reduces material to ≤40mm with multi-cylinder hydraulic protection.
- Advantage: Laminated crushing principle ensures cubic-shaped output.
- VSI6X1263 Sand Maker (Tertiary Crushing & Shaping)
- Role: Produces 0-5mm finely graded sand with low stone powder content.
- Advantage: Optimized impeller design reduces wear by 30%.
- Auxiliary Equipment:
- 3YZS2460 Vibrating Screen – Precise 3-layer separation.
- B1000×15M Belt Conveyors – Dust-proof design for humid climates.
Layout: Semi-mobile skid-mounted design for easy relocation.
Technical Highlights
- Smart Control System: Remote monitoring via GPRS for real-time adjustments.
- Durability Upgrades: HPT cone crusher’s manganese liners extended service life by 40%.
- Eco-Friendly: VSI6X’s noise reduction (<75dB) and dust suppression complied with local EPA standards.
Project Results
- Output Achieved: Stable 90tph (exceeding the 80tph target).
- Product Quality:
- 0-5mm sand (≤15% stone powder, ideal for concrete).
- 10-30mm gravel (98% cubical rate for roadbase).
- Operational Efficiency: 20% lower energy consumption vs. conventional setups.
